Gym Window Operator

A quick learner from Ohio says:
Embossed to inside Patent No 198202 US
Otherwise no identification.
From large windows in 100 year old school building.
Can not say if they are original. But at least 50 years old seems reasonable.
(graph paper behind operator is 4 sq/inch)

Hello! Your operator is old, but believe it or not they're still making this style. It seems that the closest match in our inventory is the 39-017. Look over our dimensions to confirm if this will work for you. Take special note of the arm hole diameter; ours is 5/16", which looks to be your size, but you should still check just to be 100% sure.

A quick learner from Ohio says:
Thanks for the reply.
The armhole seems closer to 3/8" - but perhaps slightly less.
I see your armhole is threaded. Mine is not.
But may be worth a try anyway.
Closest thing I'm seeing.

I see what you mean. It looks like your hole at the end is a 3/8" and unthreaded. I'm not sure about your bottom hole locations, but take a look at the 39-074 and 39-419 to see if one of these are a better match to your operator.
