Goodman’s, British Planemakers from the 1700’s has a listing for a “D. Lyons” who made planes from 1873 to 1877, but no listing at all for an “H” Lyons. I have a feeling he was a dealer, not a maker, and for some reason, thought putting his stamp on top of the makers stamp was acceptable.
If any of you have run across this situation on one of your planes, or have any information on Mr. H. Lyons, I would appreciate hearing from you.
While I am asking for help here, I will add that I am trying to put together a list of common British and American plane profiles along with their common widths from the 1700’s to today. This has, surprisingly, turned out to be a difficult task. I can’t believe that I am the first person to ever think such a list might be interesting, but finding any previous lists has eluded me. Whatever information I do come up with will be posted on the web for anyone who is interested, so whatever information you can offer would be greatly appreciated.
