extended travel balance

Hello! We can supply this balance as a custom order. Before we go any further though, I need a bit more information.

For full transparency, this exact model isn't made anymore. They stopped making it, so we can no longer sell it. The good news is that there's a modern version that works in all the same applications. The catch is that the springs are calibrated slightly differently.

With that in mind, I'm going to need you to tell me the exact weight of the sash for both windows. That's the glass panel. Any common bathroom scale will do, but we need that weight down to the ounce and as precise as you can manage. Knowing the original stamp printed on the metal channel would also be a big help. Finally, how many of these did you need?
