Ok...so let’s set the stage. And yes...I think you are right...it’s a 5” but the tag at the LGS reads 4”

Anyway, gun was made in the US middle of 1944. It was sent likely to I India which was a British colony as part of Lend Lease. It ended up being refinished by Pakistan in the 1960s.

That about right?

So....if I can buy cheap enough and turn it into a nice shooter I am probably doing it justice because I suspect as a collectible it ranks very low.
