Truth window crank

A handy person from Yarmouth, Maine says:
Can you identify the first photo? I need a replacement of this for the right side of the window. The cogs don't take anymore.
On the left side window the bars show two numbers: 20810 and P30842.
Thank you very much,

Thanks for posting, Marianne. I would start by looking at our 39-031 and 39-032. These appear similar to your operator, but check them out and see if you agree.
