I have just acquired a 1904 Ross of London telescope complete in a hand made Bob Bisset of Glen Lyon case. I came across it in a shop on Loch Tayside. It was on a shelf in a corner and without going into further detail I left the shop with it minus a few pounds. However, the scope is in excellent order though when extended it is slightly loose and I am hoping someone on the site may know of someone or company that could strip it down, clean it and tighten the tubes somewhat when re assembling it? I hope to leave my Gray at home this October and take the Ross in its place.
