Welcome back. I'd be happy to prepare these balances for you, but I'd like you to confirm one detail. Often, these balances come in asymmetrical pairs, where the balance on one side of the sash has both the 15-025 Bottom and 19-008 Top, but the other balance has only the 19-008 Top and NO bottom fitting; the balances will also have different stamps. These balances are often seen with hinge windows. Can you confirm whether or not this is the case for you? If it is, can you tell me the stamp on the balance with just the top fitting? Otherwise I'll send you a quote ASAP.

Very well. I just sent you an email with a custom link enclosed to order a pair of these 27" balances, stamped 2640, and with the 15-025 Bottom and 19-008 Top attached. Just note that these balances for a hinge window usually have a very peculiar setup, where they are not symmetrical in the way I described earlier. If you are confident however that they are the same, then see the email I sent you to order a pair. Let me know if you have further questions.
