Parts for Pan Am Aluminum window

A handy person from Vero Beach FL says:
I have most of the parts identified but the measurements on the bottom shoe are a tiny bit different. I included 4 images. It looks most like the 15-005 but that does not have the split like mine. My channels measure 24 and have 23 - 2 stamped on them. It looks like I need the S377-24 and a few 18-042. I will also need some 12 inch ones for the bath windows but I only see them starting at 13" and some 16-023 because mine broke.

This looks like just a different style of the 15-005 shoe. That split doesn't matter so much.

I cannot confirm if you have the Series 377 though, since I do not see a picture of your top attachment. We could custom make the 12" balances for you, but before we do I will need to know what stamps are printed on the metal channel for each. Let me know!
A handy person from Vero Beach says:
Here are some images of the top attachment. The stamp on 12" balances is 11-1 and I have another size that is 12" and is stamped 11-2.

One other thing. I couldn't find the glazing these Pan Am windows use on your site. Here are a few images. The short side is about 5/16" and the long side is about 1/2".

Great. That does look like the Series 377 balance, yes. Check out this request form for the 11-1 Channel Balance and this other for the 11-2 Channel Balance and fill out the rest of the information for both. Once you've submitted them, one of our representatives will get back to you with a price quote and items to add to your cart.

I'm not as sure about the glazing. It's hard to say. You could consider our 55-006 as a possible replacement, though I cannot guarantee it will work.

The pictures show that my Pan Am window uses the same channel balance. Have you purchased the parts and do they work? What about the shoe? Is it 15-005?
