Looks like a Billy Veitor gun from the area around Reelsville,In.
He worked before and after WW2,
. Made rifles from older parts and whatever worked.
If it is his work, it made it a long way from home.
Info can be found in a book _Titled X- Center Shooting in the Wabash Valley.
Author is Aubrey Williams, of Indiana.
Looks like several of his guns, but the ones I have seen were stamped with his name.
Most of his guns stayed around the area and were used in the local shooting matches.
