BSI 2930 channel balance

Thanks for posting! There is a chance we can provide you with a replacement recommendation for the balances you have but I will need to see a photo of an undamaged balance to identify the right one. The stamp from the channel will only denote the weight range the balance can hold but it will not help to identify the series you need. 

I'll need to see a photo of the top and bottom attachments on the balance as well as any that could possibly be left behind in the window channel. Please also include a photo of the pulley in the center of the balance.

Feel free to reach out with any questions you might have in the meantime.
