Back in the early 80's during my Skinhead revival years, me and a mate was in the local army surplus store and the guy told us he had a room at the back with records for sale. Wow! Nearly everything on Trojan / Pama was there! Albums & 45s from 1968 - 1972....must have been an original Skinhead who donated them. 45's were 25p each and the albums were £3 each, we paid for what we could and put the rest aside for a later day when we had some more money. Suffice to say, all the (now) in-demand Skinhead Reggae was in there...'Skinhead Speaks His Mind - Hot Rod All Stars' , all the Torpedo releases too.
Foolishly swapped the 'Skinhead Speaks His Mind' (£300+ recently on ebay) for O'Jays 'Lipstick Traces'. Doh! Did manage to get it back off the same guy, though I had to part with some good RnB.
More recently (about 8 years ago!), found a huge box of USA 45's ready for the rubbish dump, the usual Tamla/Gordy/ etc but laying right at the bottom of the pile... Embers - Watch Out Girl MGM blue/gold Issue! Nice.
