Crestline casement right hand dual arm window operator originally from TRUTH hardware 1992

From the center of the part to the wheel end of arm is 10 3/4" The window crank location is centered. There is a removable cover plate (crestlline) that fits over operator. It is originally manufactured by Truth hardware (Entry Guard) but they don't offer this style part anymore. Serial # on mounting plate is 40471 also a 6 and made in the usa imprinted in metal plate. The arm that sets in a pin has 30842R and 20810 on each section. The 20810 section is 4 7/16" long.

I took a chance on EntryGuard Dual Arm Operator 39-032 because the measurements were a perfect match. If this is what you would have recommended to order let me know or if it will not fit my window I can revise the order prior to shipping. I'm glad you provide homeowners with parts to maintain their home. Thank you!
