It's a single hung spring loaded, no channel balance, single pane window. It slides up/down but cant lock open. The shoe? is broken and i don't know how it fits inside the clip. Is this shoe part available ?

It's tough to say for sure, but I think your shoe may be a match for our 15-209. Look it over and let me know if you agree.
