Hi all: two of the crank mechanisms on my kitchen casement windows are not working. Sounds like the internal gearing is not catching and then sometimes they get totally stuck. I believe these were Marvin windows. Image 3109 has numbers on the crank handle. Can you please help me find replacement mechanisms for these? If you can and they are reasonably priced, I'll get all 4. If not, just 2.
One of the crank arms has TRUTH stamped on it.
Many thanks!
