Bill, Interesting and thanks for the connection to the Pittman company. I got a lot of hits that referenced Pittman- Bowser on google so it appears your information is on the money. Wonder how long Bowser continued? This model appears to be 1988 and is modeling an 1888 unit, where did I get early 1900s? Do you know if Bowser sold the dies? I guess the moral to the story is the trolley market was small back then and maybe was not sustainable.
I think this thing will run with a catenary connection too....
