I am looking for information on who manufactured this Stutz bike. The serial number is all numbers no letter prefixes. The first four digits of the serial number looked stamped, and the others look like they were etched in later. The way the tubing is welded has me confused too. The lower drop out on the rear is different than anything I've seen. It looks extremely well built. The crank sprocket also has me puzzled because it is the only one I have seen like it yet, the only other one I have ever seen is off a 1930s aluminum race bike.
Any information would be greatly appreciated.
