I bought an Original Model 6M from him a few months ago for what I thought was a reasonable price, £180. It was sold as being in mint condition but when it arrived it wasn't a s described, there were some flaws on the paintwork. Also the seals were shot, it wouldn't fire a pellet clear of the barrel. I contacted him & was asked to put some oil in the transfer ports & leave overnight to see if this rectified the problem. The following day I tried shooting it again& though pellets were now leaving the barrel the power was quite obviously lacking. To his credit he not only accepted my returning it, he also refunded the carriage charges both ways. He may be a bit of an Arthur Daly but he stands behind what he sells.
