FOR TRADE: Pentax A* 85mm f1.4 for F* or FA* lenses

I have .... an SMC Pentax-A* 85mm f1.4 lens in excellent condition with original metal hood. It has some visible dust between the elements, but I doubt this has any impact on the photos it produces (I've never noticed any).

I would like.... to trade/partial trade (depending on condition, value, etc) for one of the following:
An F* 300mm f4.5
An FA* 85mm f1.4 (with hood)
An FA* 28-70 f2.8 (with hood)
Possibly an FA* 24mm f2 (with hood)

If you are interested please let me know and then I can provide some photos.

I'd better add (Before I get lynched) that it would need to be a UK trade
