Ardesa Hawken? As you describe it? No more than £250. Even if the bore 'looks like a tanner up etc.' The wedge, BTW, should need tapping out with the butt of a screwdriver. It is, after all, a 'retaining' wedge and should retain itself firmly.
How long is a piece of string type question.
What sort of money would one expect to pay 2nd hand?
Bore is clean, no sign of rust, lock is positive. Some cabinet dings in stock.
Only possible niggle in my mind is wedge quite easy to push out.
