I have already determined that the balancers are:
29" Series 385 Channel Balance
S385-29
Option: 2820
However, I cannot determine which part number this is. It screws into the top of the window sash. They are brittle, and that's why the top portion is missing.

Thanks for posting. See our 18-178 Top Sash Guide pair. This looks like it might be what you have, but please compare and let us know what you think.
