50 years ago I used this tail light on my 1910. The oil font came off and was lost as I drove on HWY100 near 50th in Edina Minnesota. I then used a John Brown model 105 as a tail light. This one pictured is not marked as to manufacturer. The oil font is a two pin with a 2/516 inch fitter. Does anyone have such a light or a spare oil font?
Looks like a Solar brand.
Should be easy to find a font to mate at swap meets.
Holy smoke! I thought you posted a picture of my desk.
Sorry, can't help with the font.
