Hello,
I need a replacement window crank for a crank window that is part of a bay window. I hope these photos can provide the info you need. The crank mechanism is marked "TRUTH." and "Made in the USA." I do not know the brand of window or how old it is. The house dates from the 1960s, but the window may not be original.
Please let me know if you need me to send more information or other photos.
Thanks very much,
Chris
