Where have you found windows for your TD trailer?
I'm looking for replacement windows that will fit in a 18"x12" hole. The door is 1" plywood plus 1/8" oak inside.
I have the old vintage type with a knob at bottom middle. Knob operates 2 arms to crank window open.
Windows hinge at top.
All that is really broken are some small plastic wheels on the ends of the crank arms. When those break you can't crank the window open, & you can't keep the window shut. I had to duct tape the windows closed.
Alternately if I could get replacements for the arms (probably as a unit with arms & knob?) that would be great as well.
