Most if not all Revolvers were cut for a Linn fit arm i.e. one central large hole with 3 smaller ones around it - as Mr Pig points out. Is that what's on yours?
If so then as mentioned there are lots of Jelco made arms with someone else's badge on, including the Revolver ones of course. The decks could be bought without an arm in which case many people fitted a Linn LVX but there were other options too. As said, they are all very easy to fit.
Occasionally you see a Revolver that someone has modified to use with a different arm, usually a Rega.
They are very nice decks and underrated IMO.
