Cleaning the woodwork and bringing it back to a good standard without destroying the stamps is not so difficult. i have done this to a number of wood stocks and it looks authentic and works - waterproofed and smooth.

First step remove the woodwork and scrape any grease off. I wouldn't recommend scraping the stock wood around the stamps. The grease may be fairly heavy between the barrel and stock. This was armoury grease and should be removed before shooting.

The next step is to use hot water and a gentle cleaning agent to remove the general wax and oil and grease before starting on the dents and dings.

I use furniture wax cleaner/ stripper as the main agent as it is gentle and emulsifies the wax and grease and sweat of a thousand Gurkhas.

I rub it on by hand and then rinse with boiling water. The water is hot enough to melt the waxes and grease. Working over a basin I then use the hot water and a cruddy old cloth to rub the woodwork with more wax stripper. This rapidly will come off and the stock will start to look very matt and rough. This is good, it is the wood showing through.

I use this stuff on the markings as well, they are stamped into the wood so should not be affected by wax cleaner. However I avoid too much hot water on them.

After a few coats the amount of crap dissolving into the water will drop off. You have now cleaned the wax and oil and grease off it.

For the next stage a steam iron and wet thin cloth is needed. Some people recommend lifting agents such as bicarbonate of soda sprinkled on the wood to remove old stain but I have never needed it. You will want to raise dents and dings at this stage. DO NOT do this on the stamps, they will be harmed. Through the wet cloth gently iron and steam the wood, you will notice the smaller dings disappearing. It wil also draw out some more oil and crap. Continue for an hour or so. It is not going to ruin the history and will give a better finish.

Make sure you do the barrel channel, you will be sealing this as well in the next stage.

Once happy you have got it as far as you can let it dry.

Next day sand it with a sanding block and wet and dry paper. I use 400 grade at this stage. the idea is to sharpen up the edges and smooth the flat bits. Do NOT sand the stamps or sand hard on the edges that abut metal, such as the butt plate or where it fits into the receiver. Sanding here will affect the fit. The top edge should be straight, not wavy, hence use the sanding block.

Change th epaper regularly and DO NOT use an electric sander. This is craftsmanship.

Finish it off with something finer like a 600 grade. Use your fingers on the curved parts.

You should now have a stock that looks more or less one colour and straight. If you have dark stains they are stained because grease or oil has been allowed to soak into it long term and it will be very difficult to remove. At this point you have to decide whether to stain.

The stock is usually Italianicon walnut so quite dark. You cannot lighten it so you can only go darker. If you want it an even colour you will have to stain, personally I think this is a mistake on a historic rifle as the patina disappears but others would disagree. If you stain you will need a dark wood stain. I use cheap water soluble stain called "Dark stain" - I have no truck with subtle shades.

Two or three coats, allowing to dry between, sponged on. This will give a very dark even look, do not worry as it will lighten up and develop character in the next stage. Make sure you apply it to the barrel channel and under the butt plate.

Let it dry thoroughly somewhere dry but do not heat it or place it above a fire. You want it to achieve the natural moisture content before the next sealing stage so it does not shrink or swell later.

The choice of finish is up to you but I use pure Tung oil. it is a natural oil finish that is tough and waterproof and in keeping with the period but I do not belive it was used on the Martinis. It is also very cheap and easy to apply, just takes a week to complete.

Pure Tung oil is the one to use, not a synthetic or adulterated Tung oil finish, these are doctored to mke them easier and quicker to apply and are not as good. You will not need much and 250ml would do for 10 rifles.

You will need some fine wet and dry paper, steel wool, white spirit and Tung Oil for this next stage. Rub on the Tung oil with the wet and dry in small circular sanding movements. The first coat dilute with 25% white spirit so it will sink in.

Don't use too much Tung oil, just enough to make it look wet.

Some suggest sanding and allowing the sandings to fill the pores of the wood. Fine in theory but this is walnut and you will be sanding a long time and may not achieve what you want.

I spend some time on this stage as it will dictate just how smooth the finish is.

When I have spent 10 minutes on this I would clean it down with my fingers. I want to leave a thin film of Tung oil on it, not a glopping coat as it will not dry.

Hang it up or lean it up and leave 24 hours. I come back after 24 hours and run my hands over it, gently caressing. This will find any damp patches and spread it. Another 24 hours and it should be bone dry.

Do the same again about 6 - 8 times, reducing the amount of sanding. You should now have an even coat and see figuring in the wood, that stain having soaked into some areas of the grain more than others. If you have not stained you will not see much figuring.

The barrel channel and under the butt plate and the area that fits inside the receiver will not need this number of coats but make sure they get 3 coats. Tung Oil is waterproof and will seal the stock only if it is applied all over.

Let it dry thoroughly and then rub lightly with steel wool to give that final even surface.

You are then ready to wax. All manner of recipes are out there but I use a beeswax floor polish from the supermarket. This will protect the oil finish and give better grip. I put on 5 coats, probably does not need it.

You can then reassemble the rifle. A regular wax would be good. If you clean your rifle barel with boiling water keep it off the wood.

If you have large cracks find out why. It may be the metal parts rusting in which case remove them and sand them back down, oil them and refit. The stock bolt is often rusted and is a tight fit already. However if you can get it out in one piece it can be reused.

After steaming and cleaning I would then assess the need for further work. A crack can be glued and pinned back into its original shape. You can use panel pins but make sure you sink them in below the surface. I would use ordinary wood glue, long term it will work better than any modern glue.

If you want to fill the crack after gluing and pinning you could use wood glue and sandings before staining the stock. You will never eradicate it but it would look presentable. It would have to be pretty bad to prevent me from shooting.

I have posted picture of my .22LR conversion. I followed this method on the stock for that rifle and stained it all because the foreend was Grade 2 teak. It came out very well and is coveted by many at the gun club.

Good luck, it can be messy but getting the right wax stripper would make it straightforward.
