On a recent trip through the Maritimes I picked a vintage 1940 production Winchester 94 #1227XXX, in 30-30 with London Proof House markings and additional " NOT MADE IN ENGLAND" stampings, a rack number - # 29, a second engraved serial number on the receiver.

Also, twenty number "1"s are stamped into the butt stock denoting "kills." The rifle has a Lyman # 2 tang sight and a Marbles rear sight, and generally well preserved with existing holes from military style slings.

It was probably a private donation as it does not have any "US" markings.

Any suggestions for tracking the history of this gun is appreciated. I'm also trying to get an idea of how many of these firearms came back from the "Lend Lease" programs and ballpark the value of this firearm.

Cheers!

I have never seen any records of the lend lease and donated weapons. . Value is the same as any Model 94 in equal condition and vintage, plus whatever the buyer thinks the history is worth. It is important to me; I know others who don't care about history.
We do see Pacific Coast Ranger 94s from time to time and those do bring a premium.

you could try for a factory letter from Winchester or the cody museum.
it would tell you where and to whom it was shipped.
