Hi. You are not breaking any rules whatsoever, as yes, imho (and many others), this is a collectable air rifle, so it has every right to be advertised here, too . To this end then have pasted a link below to your main advert, as in the main sales section, where (f.a.o. any potential buyers) it appears with photos, and is priced at £150 plus post. Suggest any interested parties post on the main advert as in the link below, and to MAJORPAIN I say good luck with the sale . Atb: G.
