Shotshells, here is what I found

I'll just make a new post rather than muddy up another one. Also this subject will touch on another thread about a Remington Model 11 below that I answered part of.

They are definitely WWII !! Used to teach lead during air gunnery practice on the skeet field.

Any extra value to them other than a nice box of old shells ??

These sell on GB for $50/box. http://www.gunbroker.com/Auction/ViewItem.aspx?Item=367137084
Being new in wrap you might get a bit more

Excellent find!

GENERALLY, iF they were brass OOB, they were almost marked on the outer foil. The No. 6,8,9 chilld shot and trap boxes were usually wrapped without outer markins as shown in your photos.
