casement window cranks

A quick learner from near Santa Fe New Mexico says:
Have several non-working and cranky (sic) casement window cranks. Want to make sure what I order will fir the windows I have. These are for a log cabin in New Mexico, which are probably 30 years old. Thanks. Bill

Hi, Bill. I would start by looking at our 39-031 and 39-032. Carefully compare our dimensions to yours to confirm that everything matches up.

A quick learner from near Santa Fe New Mexico says:
Argh. There are no measurements listed on your site for the 39-031 not 39-032, so "compare the dimensions" offers little help.
