Looking for replacement operators for what I think may be Hope's steel casement windows circa 1939(ish). Pictures are below - stamped inside the operator cover are the words "Parker" and "Erie." Eire is stamped directly below Parker. A google search on those words and windows yielded little info.
The house also came with a tin can containing the extra steel gears you see tied together in the picture below with a 1960 note to a handyman thanking him for rebuilding some of the arms.
One of the reasons I suspect the windows are Hope's is that the closest replacement I could find is a Hope's replacement, although it is not an exact match to what I have.
The gear teeth in the arms, pins and spindles are in various states of wear, rendering about half of the windows in my house inoperable.
Can you please help me find a replacement?
Thank you,
Michael
