you might expect £100 but you're not going to get it,imo it's worth about £30 with that damage.i've just bought a mk2 in gwo with its etching clear and visible for £50.

Oh dear,

I have a MK1 and MK2 at Melbourne on Saturday and was hoping to put a deposit on a yacht with the proceeds

Apologies for slightly off topic, but when did they stop doing the conical piston head ? I'd like to buy an older one, with scope rails, but not with a conical piston. I think I need a mk3/4 ? However for £50 for a good condition mk2, I'd take it regardless of piston head - I'm sure £100-£150 is a very safe range for such a gun !

Mk1s and Mk2s had the conical piston head, not sure about the Mk3 - some early ones may and some later ones may not. Mk4 on do not!
May be possible to fit a mk1/2 conical head piston to Mk4s on (or vica-versa) - not sure, perhaps someone who has done this or knows could help confirm?

i bought it from a shop too,he doesn't like older stuff as it's outside of his sphere of knowledge.

The conical piston disappeared with the Mk4, but was replaced with a rather stupid twin O ring design, it didn't get down to a single O ring piston head until the Mk6, but then it still has a largely pointless buffer washer taking up 5 mill of swept volume. Putting a sensible piston head on anything from the Mk4 onwards is simple, you could do it with hand tools as I have proved a couple of times in my youth.

so was that just down to cost
or is the latter assembly more efficent

Reading through this... where did you all guess it was a Mk2? It has a but pad missing so must be a MK3/4 onwards

We didn't - the first post was about a mk3 or 4, the second post was about what was paid for a mk2.
Two conversations going at the same time!

I suppose its only saddo Airsporter nuts like us that would notice.
