Painter777,
Thanks for being helpful. It's appreciated. I have attached here 3 pics of the repair. It seems strong and well done - but I don't braze. Thanks also for the Ebay contact. I looked and he has lots of stuff. I would prefer to treat this repair as something possibly USGI if at all possible. Correct is good but original is better. If and when I sell this carbine I need to be forthright. I know that WW2 martial arms production was a crazy fast paced thing and all kinds of things did and did not happen and the documented data for Carbines has not captured everything.
Thanks again
