Ron,
1. I do believe the stock was painted green. There are a few marks on the stock which seem to show a grey underneath as a molded in colour. If it is paint though, it certainly is bonded well as it doesn't easily come off!
2. As above, I believe it to be a grey base however on reflection that could also be primer.
3. Yes. Black with a basket weave pattern and the word McMILLAN on the back surface. Sides are smooth. There is also a black base or spaced between the stock and pad. I would say to is approx 3/8 inch thick.
4. Sorry but I don't have scales handy. It is a heavy fills stock though.
A few other things;
- under the cheek riser, the number 459 is marked, same as in the barrel channel. I did wonder if that was a partial serial number to link the stock to a particular action.
- I believe that the stock was bedded more than once as there are two colours of bedding compound and the quality of the bedding job seems better in some places than others.
- Somewhere around here I also have a Parker Hale trigger like someone else posted a picture of. The rear action screw area does seem to be bedded for such a trigger however back in the day that was a pretty common option on Mauser '98 rifles.
- In a few places on the stock, there are small bits of a light green paint marks (bottom of butt by recoil pad and around top of action area)
- There are visible rub marks are the bottom end of the forestock from a bipod base mounted on the rail I assume as well as fainter wear right on the blunt end of the fore-end.
I appreciate everyone's help in figuring this out.
