Vinyl glazing for old aluminum single hung window

Question

I can not find a brand name or any markings on windows. They are about 30 years old. I ordered item # 55-029 but they will not work. The lock in bead seems to be on the opposite side. The first picture shows one of them installed

I'm sorry to hear that the 55-029 didn't work for you. That would have been my top guess, though. I'm not sure if we sell anything closer.

Can you go into more detail as to why it won't work? If the issue is that the tab iis on the opposite side, wouldn't flipping it over give you the proper orientation?
