A quick learner says:
I need a RH window operator.

On my handle there is a no. D-198202 n.s.

RD 1963 Can.

I guess they used that Pat No. for a lot of these operators.

Everything I am looking at has different holes.

Greetings. Please compare your awning operator to the 39-056 or 39-259 . See if either match what you need.
