Eagle Casement Hardware

I'm a member of a condo association board looking to replace the hardware on many (maybe 100) Eagle casement windows installed in the early to mid 1980s. Many have the short arm and the slider at the corner of the window rusted out. We're able to find new sashes locally but can't find the hardware lately. Looks like a Truth mechanism with the numbers 30382 on the short arm. Thank you! John
