20 x 134 mm Dummy

Found this item today. At first I thought it was a 20 mm HS820, as the overall length is identical, the "case" length is however only 134 mm.

Any ideas?

I have an almost identical dummy round, but with a thinner, integral, brass rim - yours seems to have a separate steel rim?

Mine is for the Swiss 20x139 FMK 38 and Flab Kan 38, the predecessors of the HS 820/Oerlikon KAD. The main differences were the use of a brass rather than steel case and the thinner rim. The thick rim suggests that yours probably is for the HS 820.
