The worst part is that it seems to have been a sort of 'general service' badge into the 60s + 70s and therefore fairly common.
I was in Luxembourg last week in and went to an army surplus, I asked the woman behind the counter if she had any and she said that it was 'forbidden' to sell metal cap badges - is this true.
The worst part is that the museum in Diekirch has 20+ of that type
on display.
Ho hum....
