Need to find some 78's....

While I'd been waiting for the gramophone to arrive in the post I'd been desperately trying to aquire some 78rpm records to test it with. There are plenty on eBay, but when you add on postage costs they start to become very expensive! Someone suggested looking in charity shops....and sure enough after trawling through most of the local charity shops I finally hit the jackpot managing to buy approx 25 gramophone records for 50p each. The weight of them is unbelievable! Apparently they are made from around 70% limestone/slate....so it was like carrying a bag of bricks!
