Oldfart: I apologise for my comments on the basis that I haven`t got the right to bag someone on here. Like Bob Homewood, both my father and my father in law Barry Pointon, have a wealth of knowledge regarding a lot of these topics, but unfortunately they aren`t going to be around forever. If someone says `no, it was this or that' accept what they say, and move on. As GD66 and Rod have stated, this whole forum is for all our enjoyment and benefit, and I for one really enjoy some of the articles on here. Having the ability to look back with like minded people is far more beneficial to everyone than arguing with a select few. Enough said......
