Sorry to hear that Jon.
I think they are quite scarce..There’s been one on egun for about three years at €750 but it’s never sold.
There is a defective one on there now for a ‘buy it now’ of €250 but it has parts missing.
A nice one sold on catawiki for €750 but that’s a worldwide site that gets high prices. (Sometimes twice what we seem to pay in the U.K.)
I’m sure someone else will have a better idea of the going rate here.
Cheers,
Matt
