I just bought a 13'
boler a few weeks ago -- 1970 -- and have been doing some cosmetic work to clean up the inside.
The small 6" high
awning window in the door is damaged (looks like someone tried to jimmy it open), and I would to replace it.
If anyone has a spare window, I would be interested in buying -- will pay shipping.
As a short-term fix I could replace the window operator, but haven't found a close enough match from anywhere that will ship to Canada -- the worm gear and the teeth on the operator arm are both shot, so window doesn't stay closed unless it's wired shut.
