He was an ex RFD who had built up a collection of several thousand air guns as a retirement fund. Not a bad bloke to deal with and I actually got some very good stuff off him. His advertising and prices might have been a bit surprising but ,talk to him and some very good deals could come out of it.,
I think it's people who hadn't dealt with Glynn slagged him and gave him an undeserved reputation.
I was quite happy with 2 reasonable pre WW1 Long Toms ( advertised at £200 each) for £200 the pair, A working but little tatty Gem advertised at £100 but sold to me for £45 and a tidy Medium precision advertised at £200 that I got for £100
