Operators need replacement

Question

I have several windows where the operators no longer work. The hardware on the casement windows are all manufactured by Truth. I found 2 types with different numbers imprinted on them:
Most have 20810A imprinted on them and I don't see any ither number on any other part. Ther are two that also have number part 31538A on another peice with the 20810A part.
I also have 2 windows that have 29810 and not 20810A.
what other information would be helpful?

Thanks for posting. See the 39-031 and 39-032 Dual-Arm Operators. See if the dimensions match what you need. For covers and handles, see the 39-114L and 39-107 sold separately.
