Worm and Gear operator replacement

A home owner from Portland, OR says:
Just curious how much a replacement "Gear and Worm" ? operator from H. S. Getty would cost. I have 1 broken one, and one that could be replaced.

Hello,

Your operator resembles the 39-002. Take a look at the dimensions below to confirm that they match your assembly. We also offer the 39-001 opposite-handed version if needed. Thanks for posting!
