Here is an unusual find in this full case of new primers. This appears to be an unopened box that measures approximately 15" x 17" x 9" high. It is in fine condition with the exception that the wood on bottom has extensive old worm holes. Box is marked in red "25,000, New No. 4 Primers / Handle Carefully." Other Winchester markings on reverse side. I believe the No. 4 primer was for 20 ga. brass shot shells, but probably for other loadings also. I've sold new, light gray, 100 ct. primer boxes for $15. to $20. a box before and with this case there should be at least 250 of those boxes inside, plus the wood case itself. So, we have quite a retail sum here.
