I could use help identifying a replacement for this window balance and shoe

Question

This is part of a large, tilting, vinyl, two panel window. The only identifying part numbers I can see are on the metal guide, and they are "30D" but I cannot see the manufacturer's name.

Thanks for any assistance,
Mike

Hey, Mike. See our Series 770 balance and 15-135 shoe. This hardware appears to match what you show in your pictures but see what you think.
