fake drum serial?

[G.T.]

Hi to all, in working on this recently established reproduction drum, I'm pretty sure there is way more to this than we are aware of? Forming dies to make these parts are not just lying around everywhere? The repro drums are a very close copy, and well made with regard to gauge of metal and accuracy of formed parts?
The tells that give it away are consistent and once known, obvious? But the question is, why? I think the parts were made on left over original equipment somewhere , sometime ago..... They would have been better off to not mark them or number them at all.... best to all, til....lat'r....GT...
