The Baltimore Streetcar Museum is looking for 3 push buttons (photo attached). These are the passenger signals on our 1902 11 bench open car. If you could check your stock of junk parts to see if you have any it would be appreciated. I know these were produced for a long time. They were original equipment on our 1902 cars and were still offered in 1911 as they are in the 1911 Electric Railway Dictionary. Thanks in advance for checking.
