Metal piece marked 27 4 BU CMC 4 fell off when opening and closing the window. The window pane eventually fell off entirely. Seems like a need a new metal piece. Can you help?

Thanks for posting. This looks like either an S380-28 or S385-28 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe, as shown below. Measure your old balance's shoe depth to see what matches best. In either case for a stamp option choose 2740.

Comparison of the S378, S380 and S385 balance shoes.
