Help with military shotgun cartridges


#1

Hi everyone!
Can someone provide information on WW2 US military shotgun cartridges? I have located a box I would like to purchase but am having trouble finding information. The cartridges are UMC Rem, 12 gauge, brass, 00 buck. Ten cartridges in the box. Lot number on box is 78-37. Can any help with date of manufacture (is it 1937?)? Also, could anyone suggest an approximate offering price for the box of ten cartridges? The box is in good condition.

Thank you,
Steve
