Excelsior Serial Numbers

Excelsior fans – does any one have an Excelsior twin with a serial number between 60000 and 75000?

I've been gathering Excelsior and Henderson serial numbers for a number of years; I began with the intention of validating the Ballak numbers and filling in the holes. I've currently gathered well over 800 Excelsior numbers from various sources. The numbers are fairly evenly spread over the full range. However, there are a couple breaks in the sequence. The largest break is from a little over 60000 to 75000. So, anyone out there have an X with a serial number in that gap?

About what year(s) would those numbers cover?

That is what makes this break so interesting.... around 1915. It appears to come between the 1914 motor, the last of the Robie-Meiser designed engines, and the 1915 model, the new motor designed under Schwinn management. Further, it seems to come just about at the time that the factory was moving from the Union Street facility to the new Schwinn Building on Cortland.
