Does anyone know if the Webley MKV hinge pin screw is the same as the MKIII screw or not?
My MKV is missing the screw and I don’t see any for sale.
Thank you.

I should have thought Peter would have picked this one up and run. I was waiting for that...
I looked at it BAR but didn't know what thread it was. Probably some mickey mouse thread that the Midlands gun trade, including the dreaded Parker Hale and AJParker et al kept to themselves. And in doing so, ensured that purchasers always had to go back to them for spare parts.
That said, it wouldn't hold me back for more than a millisecond I have to say. Just machine up another matching axis pin and securing screw with a thread that suits what tap and die set I had handy. 4 or 5 BA looks sort of similar...... 30 minutes at most. I found that real Armourers were pretty versatile blokes with a 'can-do' take on life. Even more so when it was to their benefit!
That follows. And so does the rest. I'd make a replacement on the lathe and be done...
There you go Vincent, the wisdom of the crowd theory again!
Oh we're WISE...! :rofl:Quote:

Thank you, Tom.
Those dimensions would be a great help.
I bet that the threads are a mickey mouse size...........
Do you mean something simple or non-standard like Whitworth? Or something we've never heard of?Quote:

I see pictures of some Webleys that don’t have this screw. It looks like they have a pin that’s not threaded on the end. Does the screw hold something or is it redundant? :confused:
I think the other meaning for "mickey mouse" is proprietary, usually done to protect a formula or part from being easily copied by a competitor. Maybe a little odd for a contracted military arm. The dimensions for the screw are; major OD of threads= 0.134" @ 36TPI and a threaded length of 0.28". The screw head fits the recess in the frame and is slightly domed. These dimensions don't match any standard British, American or metric thread I can find but would be closely analogous to an American 6-36. I think Peter's definition of mickey mouse, fits the bill.
There is someone on ebay selling 6-36X7/8" steel slotted screws with large heads that could be easily shortened and the heads altered to fit I think. They want about $13 for four of them. This screw is somewhat redundant in that if the coin slotted screw on the left side is removed the hinge pin is free to move laterally and possibly fall out. If the coin slotted screw is in place nothing can go awry. Best. Tom
Thank you, Tom. That is very helpful.
My son-in-law thinks he might have found a screw online. We will see if it works when it gets here. I will get the one on ebay if it doesn’t fit.
Since the screw is redundant I am going to clean it and fire it.
Thanks again.

Mickey mouse is a technical term used throughout the REME for things that don't seem to fit where they should. Or anything that is a tad puzzling! Like Parker Hale thread systems for instance - and pre No2 revolver Webley now that I come to think about it! Devised by someone on his last day in the office who doesn't give a sh, er...... damn about what follows later.
I'd just make new parts using that other famous mickey mouse thread, the BA system!
Hey, there's nothing wrong with Whitworths BAR. My Norton is full of them!
Agreed, just meant they weren't standard...(around here)..Quote:

The answer is NO. The MKIII screw is smaller.
With the length of this thread already, are you saying that a newly machined axis pin and screw with a known thread wouldn't suit your needs Vince? That'd be like saying that a No4 couldn't be repaired because the rear trigger guard screw was missing - but you're sat on a box of foresight protector screws. Or that the trigger axis pin was worn out - but you have a few fore-end nose cap pins on the bench.
No Peter. I am not saying that. The screw is a redundant part. I can shoot the pistol the way it is. I don’t need the screw. It would be nice to have, but it’s not necessary.
Peter, what model/year Norton do you have? I am a long time rider and restorer of British motorcycles if fifty plus years is a long time. Depending on the vintage (maybe), your Amal carburetor and possibly the Lucas components likely have British Association BA screw threads. For those that are not aware, Whitworth was the first standardized thread system in the world so a little slack should be given for any perceived design idiosyncrasies. I'm pretty sure I have more Whitworth threaded vehicles here than metric or American so I am a little partial. Off topic. Sorry. Tom
PM sent re 750 Commando. Never try to out-Norton a Commando....... Kind regards
