SWISCO - The Replacement Hardware Authority

casement window operator

A quick learner from los angeles says:
I have a client with Kolb & Kolb casement windows.
The operator has a part # stamped on it:
Truth Entry Guard 30851
The long operator arm is appx. 8"
I will need to order several, both right-handed and left handed.
Without a photo, are you able to identify?
It looks like your part #39-031
Am I on the right track(so to speak)?

Tom from SWISCO responded:
I'm afraid we cannot identify this part based on that stamp alone, no. You say it looks like the 39-031, though. When you compare the dimensions for that part to your own, are they identical? If not, where do they differ?
A quick learner says:
Went & took the old one out. Yes, this does indeed appear to be the correct replacement. I'll go ahead and order.
