Replace skylight mechanism

A quick learner from Waldwick, NJ says:
Serial # 76782

Would part #39-379 be the replacement part?

The 39-379 does look close, but I'm afraid I cannot confirm. There were many skylight operators that were made similar to this that were unfortunately discontinued. You will need to carefully compare our pictures and measurements to confirm if this can work. Unfortunately, I cannot guarantee that it will.
