Most standard ones will fit from 600/750 and 900 and they probably all have different part numbers. The really early ones didn't have a chamfer and those are the ones sought after for the really early '93-94 bikes but the others should be readily available not much $$ I'm not sure that the ZDM is a Ducati part number but maybe some sort of type approval code?

Ive already found out about the "Hens Teeth" early ones and I know about the chamfer. ZDM-A21 is something I have seen stamped on them looking on ebay
The long part number seems to vary, although the can looks just the same, I guess thats what youre talking about it being shared between models
Ive seen 573.1.050.2E or 574.1.050.2B

Yours is 95 model year, so the Type Approval writing will list the M900 and M600, but not the M750 as they hadn’t started production then. The silencers will have the chamfered underside too, as they were introduced mid ‘94 model year.

Correction: They only list the M900, until the M750 was added. M600 have a different legend.
