OK, Here We Go

[Marine A5 Sniper Rifle]

Jim, who is the owner of the bases as pictured in your 3rd post in this thread? The blued ones look like reproductions, while the phosphated ones look exactly identically to the ones I have (staked screwhead markings).

I don't know. I have downloaded dozens of pictures over the years. The purpose of the picture was to show what a MN base looked like and that one filled the bill. I might point out that Niedner's bases were quite different from WRA's. The one rifle I have seen I believe to be an original (of the 150), has its bases soldered onto the rifle. You can just see the silver line.

The scope pictured below that bases is clearly a British A5 scope.

Yes it is. Still the same mount.

The Brits also put a lot of red colour on those scopes plus someone even filled the markings on the screw with colour (something what I sniper would never do), ....

Not true.

....hence I wouldn't be too sure if this still is original Winchester.

I have no idea what you mean by this comment. Please explain.

Tom's rifle looks marvellous, I'm really envy of that piece! And I wouldn't mind seeing a picture showing the inletting of the handguard to make the scope removeable, since there seem to be quite some variants.

All the originals I have seen are identical, Niedner and WRA. The variance comes from later day fakers not knowing what an original looked like.

Tom's rifles are remarkable. Tom is a nice guy and I miss his posts.

Are the bases on his rifle phosphated or blued?

Neither, if they are original.

I have a yellow lense adaptor myself which seems to be for WWI British scopes, since it came with a British scope I had bought. I however believe they wouldn't be that much of a help, but it might had been worth the try...

I use mine on my hunting rifle, and it works extremely well. I am good for 30 min after sunset and 30 min before sun rise. The scope combination is excellent in my opinion. The British may well have used them, but so did the Corps.
