yes, its always a relief you just never know! When I buy stuff like this I always think the worst, and factor in what it would make in parts if it was not salvageable. if I can make what I pay back in parts, I take the risk!
Last year I popped into the scrap yard where I buy my brass and alloy for the lathe, he has some nice stuff in there as he has a contract with an aircraft parts manufacturer and all the bar ends are marked with the material specification!
on the weight scales was a Honda 4 cylinder engine that someone had just weighed in for scrap... I didn't know what it was, other than a Honda but asked if I could buy it. the guy sucked his teeth and said its got to be £50...
I had no idea what it was could have been a 400... but after some research it was a 2003 Honda CB 750! I stripped it down and it was good condition!! I sold the parts on Ebay. didn't realise how desirable the parts were!
