Hello! This looks like an old Pan Am balance. I believe we can make this, but it will have to be a custom order due to its configuration.

Please give us a little more time to confirm its availability and I'll get back to you ASAP! In the meantime, can you tell me how many you wanted to buy? I will need a count before we finalize anything so we may as well get that now.

Thanks! That's all we needed to know. I'll email you two purchase links right now: one for 2 balances, and another for 4. Each will include a price quote.

Note that these balances will be made according to the information we've gathered from the stamp, which indicates a 12-1/2" long metal channel and a calibration for a sash weighing 3 through 6 pounds. They will also have a 19-035 top and 15-007 bottom nylon fitting. 

You may want to triple check these details to ensure that they align. These are very old parts and there's no guarantee that the information we have on record is going to be accurate to the real thing. It's always a good idea to check the hard details just to be safe.
