window operator replacement

A home owner from Punta Gorda, Fl says:

Hello I am trying to find replacements left and right for the depicted operators. They have the following #'s inside the body. Pat. No. D-198 202 U.S.

RD 1963 Can. 11500-4. I believe these are the numbers some are obscured.

Thanks in advance.

Thanks for posting. To start, see either our 39-074 & 39-075 Lenahan Window Crank, or our 39-016 & 39-017 Pan am/Daryl Window Crank. Without knowing your hole spacing dimensions I can't say for certain which is the closer match, but take a look and see what you think.
