Many thanks for your prompt reply and information on your Classic key. The schematic diagram did help, so, with that and the image of the key, I was able to adjust the key.
Incidentally, both my friend and I have always used a Vibroplex bug. He recently had to change to the electronic keyer due to arthritic fingers/hands. If the future dictates a similar decision for me, I will certainly be looking again at your fine selection of Begali paddles.
