I'm afraid that number doesn't tell us what you have. We will need to see a picture of the part in question in order to find a match.
A quick learner from Jupiter Florida says:
Sending a picture. These windows were made by a company called Alcan and installed at least 30 years ago. Windows are in great shape but we wanted to replace the rollers.

Therma was the probable manufacturer of the horizontal window/part

I'm not sure if we can supply you with this exact roller. Take a look at the 87-160, 87-187 or 87-219 to get started and see if you can adapt one of these to your window. I cannot guarantee any will work, but I haven't been able to find anything closer. Also look at the 87-058, which is just the wheel by itself. Maybe you can just reuse your old housing.
