Greetings. Unfortunately the company that made your balances went out of business. Looks like you will need custom Series 770 tilt balances with 15-014 knife lock shoe attached. We can provide this for you, but we will need a little more information first. Based on your stamp codes, we believe the metal channel length of the 32-E-50  will be 33"; for the 36-E-50 it will be 37". Please confirm these lengths to be sure.

A contractor from US says:
Yes length are correct, what is shipping time to Greenwich CT.

Shipping times will be shown in check out. After you put in your address and zip code, you will see a variety of options to choose from. We ship both USPS and FedEx.

As for the balances, that should be all the information we need. Please give us just a little more time to confirm availability and we will email you an order link and price quote as soon as possible.
