27 4 AW CMC 2

Thanks for writing in! The stamp from the balances tells us the weight range a balance may be able to support but they do not tell us the series, unfortunately. To confirm the correct replacements, I'll need to see photos of the top and bottom attachments on the channel. I'll also need to see the bracket connecting the spring and the cord (string) in the center of the balance.

Please let me know if you have any questions!
