WS double hung with the old foam liners. Probably 20 years old. Looking for some pivot pins. I know they make 3 or 4. I can get exact measurements later but this is the style and probably the only kind that looks like this. Newer models had step ups on them. It protrudes about 1/2 inch. I'm a professional.

Hello, thank you for posting,
The closest we carry to your original is the 26-150 pivot bars. Please review the style and dimensions to see what you think!
