Ive not seen an air gun at a bootsale for years, they seem to stop it these days, but found one today. And what luck, an airsporter. Pick it up, its a mk1. Pitted and painted black, wrong back block, trigger didnt feel great, stock had fallen apart and been badly glued back together and badly finished. Rear sight was half missing, didnt build/hold any pressure against the tap. Didnt look like there was a single decent part left on it.
Price? £80 lol.

obviously I walked away.
