Collar Disk, ground find

[AB45]

Hi

I found this Collar Disk today. I would like to know if it is WW2 or Post WW2.

Given the backing bar, it could range from 1943-1970. Type V disc were in use for that long, and then replaced by Type IIIb discs in 1970. If the backing bar is made of zinc, its probably WW2 issue. Hard to tell with the corrosion present.

I agree with Major Z, I have seen a few with the heavy think rolled edge like that. That were WW2 era.
