Also, Ken Hamilton made that illustration for a Mercury custom he built at the time for SAE. I saw this fantastic model with the working windows and all at a show back in 1987. He posts on this board, and he was the inspiration for me to tackle working windows.
It would be interesting to see if he still has the model, and if the windows still work after 25 years!
I just ran across this thread. For the record, the thread has never jammed or broken and the mechanism has worked perfectly for 25 years.
It's nowhere near as hi-tech as Bill's incredible window unit, but it got the job done.
Thanks for the kind words, Bill..!
