The Woodin Lab collection also has one and this is the first place I documented it. Back in the early 1970s, I visited the Jeff WerBell of MAC, and he was showing me some very interesting things they had. On a shelf was a wooden block with nine cases in the nine holes in the block. The first case had the “9mm 1” headstamp, the second “9mm 2” and on until “9mm 9”. He knew they were from Amron, but had no idea what they were for or why. Unfortunately, he didn’t offer them to me!
A few years ago, I went back to see Jeff here in Atlanta. He and his brother are long out of the Firearms and ammo business, but he did take Bill Woodin and I down to where he had the ammunition residue was stored. These 9 cases were not there and Jeff has no memory of them.
I have no reason to doubt that the 1 is for the first lot, but I don’t have a theory for why they should have a block with headstamps 1 through 9!
One of many things I don’t understand…
If anyone has, or has seen this block or the cases, please let me know.
