Hang onto your head and check out the vintage ammunition in this link! They have a Single box of 20 rounds like yours for...get this....$450 bucks! And they don't even have the even rarer wooden box! Maybe you could contact them?
"Much that once was, is lost. For none now live who remember it."
thank you for the info
For one box ? You'd have to be insanely rich to spend
that kind of dough - or just insane.........
