When did "DRGM" markings phase out?

[Scott C.]

I saw a 4-place, tab-back, TR medal bar at the SOS that was stamped DRGM on the back plate. The bar was: '39EKII/Heer 4-yr/Austian occupation/Czech occupation. The bar appeared 100% legitimate (even wear & age, no sign of messing around with the tabs, etc).

Did the local German hamlet medal bar/ribbon bar makers use DRGM-marked components until they ran out, or was there an official cut-off date?

Thanks.

Theoretically it could be used until the end of 1952. Jim
