Our handyman thinks these are made by Weathershield, out of Medford, WI
As pictured, likely "Crank 1" and "Crank 3" are likely the same.
Hopefully we can order these 3 window cranks from you guys!
Thanks,
Sheldon

Hello,
Take a look at our 39-171 and 39-172. Look over the dimensions carefully and see if this type of operator is what you need. Also, see our 39-398 sash stop if you need to replace those as well. Thank you!
