Mate of mine picked up a very rare paire of toy train carriages,made in Germany in the '20s for £6.he got £4500 for them.Shitter was,they had sold the engine 10 minutes before he got to the stall to some kid for £5 and if he had got that as well as the carriages he would have got about 20 grand!! .He spent weeks advertising in the local papers trying to track it down but nothing!Still.not bad profit for a few minutes browsing!
