I recently got an email from a young man named Paul who is working on restoring a Bethlehem Steel 37mm cannon as an Eagle Scout project. The gun is sitting outside an American Legion post, where I expect it has been for many, many decades. It appears to be mostly complete with the major exception of the wheels, which have disappeared one way or another.
Paul wrote to ask me if I have any dimensions on the wheels – which unfortunately I do not. I did a video on one of these guns a little while back, but I managed to misplace the owner’s contact information. If anyone has access to one of these guns or dimensional data on them and would be willing to help out with this project, please let me know and I will but you in touch with Paul.
