Jim,
I'm shooting from the hip here.
If I had to memorize every Safety Data Sheet on every material we use.....I'd never get anything else done.
Un Boiled LO is actually just Raw Linseed Oil that starts out as a type of natural Crude oil. Then is warmed slightly and allowed to stand in tanks up to two years. After the impurities settle, the top (Raw) oils are pulled and used as a Raw Linseed Oil.
Actually BLO isn't boiled. It's produced by blowing air through the oil ( Oxidation) and heated until thickened along with having dryers added like Japan dryer. It just a mix of Raw Lo with added oil based solvents and metallic dryers.
Since the use of Alkyd based oil paints, Linseed oil has mainly been used as a binder for paint pigments.
Now with the newer improved Latex Acrylic lines of paint......the oil bases are being used less and less except for Industrial finishes.
There are many versions of Linseed oil...one called Stand Oil is heated to aprox 600 degrees F and held at that temperature for a number of hours. The change is a molecular one, called polymerization. Stand oil is a heavy, viscous material. It can be thinned to a painting consistency by mixing it with several different types of thinners. It is one of the most useful ingredients in varnish.
Spontaneous Combustion Warning.........
Best ways to discard rags would be to submerge in a bucket of water.
Just for kicks.....on a hot sunny day, we'll pile them up on a dirt mound and bet on how long it will take to combust. Usually they'll start smoking in under 10 minutes.
I don't care for Turpentine. I use mineral spirits. Low flash point, just keep away from open flame.
I thin the BLO in the tank 50-50 to start with...as it warms and thickens I keep adding mineral spirits as needed. When applying coats by hand I use BLO full strength. Last coat is Tung Oil and cut 50-50.
That's about all I know about BLO and they're are still other versions of it.......
I'm trying buddy !
Gotta get to work........spraying varnish tonight !! WOOOO HOOOO

Great info about a great job.
Have you run into stocks that seemed to have non-US wood putty in them ?
I encountered a Blue Sky a few years ago that seemed like it had been re-furbed as a ceremonial gun. The bottom & sides of some gouges were lined with putty. Sadly someone had ( freshly ) sanded the right side of the high wood stock between the oiler slot and the grip area -- destroying the stamp & the slogan. The only US stamp left on the the outside was in the sling well:
TRIMBLE
. . TN
ETA:
The carbine was close to like new as re-furbed.

campperrykid,
I did run across this Korean returned stock that had what may have been a bullet hole thru it. Not sure, but some here thought thats what the repair may have been for. I had the old camera back then and couldn't get pictures any bigger.
The patch was like a Resin, you'd find on Fiberglas repairs.
It was a NPM stock, made by Trimble. Can't remember if it was a hi-wood....thinking it was a cut down, but not sure.

Painter, you wonder what they would say if they could talk!
I bought an 1889 44 WCF Marlin levergun that appeared to have a bullet hole through the top edge of the comb of the stock. The path went from front to rear, left to right at an angle. I bought it from an old boy that just listed it as having a damaged stock. Always wish I knew they story on that one. I should see if I still have a JPEG of it.
