Bubble seal for awning window

I think these are Anderson windows from the mid 1980's. I can't find markings on the corner of the glass. The seals are literally falling apart. The one piece intact that is shown in my fingers is approx.9/32"-5/16". I have 9 windows to do once we determine the correct product. I'm thinking the product is similar to the 58-055 or 58-187. The color appears to be beige or tan but that could just be the age of the seal. Every time I try to pull the kerf out it just tears off.
