looking for replacement part for original Truth Hardware

A contractor from Los Angeles says:

Hi I am Jeff Bozem an electrical contractor from Los Angeles. A homeowner asked us trouble-shoot & repair/replace non working problems. We have traced problem to the TRUTH Hardware mechanical operators. I have included pics of actual unit...the following info is stamped on actual Hardware TRUTH, Pat. Canada 1986,U.S. Pat. 4505601, Made in USA, 45206,4....on the arms there is 30896. I can include more measurements on another web-site I found which looked exactly like my part & they described as TRUTH Hardware 16-1/4 single pull awning operator or a 21-1/2 single pull awning operator....but these units were opening & closing "CASEMENT-WINDOWS" (not awnings)

Thanks for posting! Take a look at our 39-083 or 39-140 operators to see if either of these match up to yours. It will ultimately come down to the elbow-to-elbow measurement. Let us know if you have any questions.
