Casement Operator

A purchasing agent from Princeton New Jersey says:
Hello, I'm the administrator at a church and the sexton has brought this casement operator to me. We need two RIGHT HAND and one LEFT HAND. Attached are photos of the left hand operator; it has no identifying marks on it. However, the sexton found the word 'Ualco' on an operator in another room so we think it's correct. Please advise what we should purchase. Thank you.

Thanks for posting, Sara. Please take a look at our 39-044 and 39-045 Getty operators to see if they may work for you. Keep in mind that these operators do not have the off-set at the end of their arms, so you may also need to replace the track. Please make sure to look at the related tracks 39-501, 39-504, and 39-512.
