Why would they have been skilfull 20 years ago? I use the same tools – But a lot of folk even now, claim there is no difference in quality. I sold the Bidston Hill in 1972 for £16 and considered myself well paid. It showed up on Ebay several years ago, and went to the US for £400. I sent the buyer a picture of Donna Francisca, and he said there was no difference in quality as far as he could see – no improvement at all!
