Sayre & Company ad from November 26, 1948 issue of The Terre Haute Tribune says their Duplex bicycle was introduced in 1911:

1341239


1341240


1341241
 
Another reference to remodeled Sayre and Company store. Founding date of Hatfield-Hughes different than ad above (1893 or 1895?). Reference to Hatfield-Hughes selling high wheels in 1895 not correct as safeties had taken over by then. It does say J. E. Sayre purchased the business in 1906. Cannot find anything on him before this date. Will keep digging.

From November 28, 1948 issue of The Terre Haute Tribune:
1341314

1341315
 
Another 1911 connection might be the patent stamping. Pope sued Schwinn regarding the November 13, 1888 Smith-National patent # 392,973. That suit was dismissed on October 13,1911. Not sure when Pope started that stamping; but one might assume that it was somewhat less necessary after about 1911.

Serial number 110975 looks like one twice previously posted by @popmachines.

So thanks to SA here is the earlier post on his bike https://thecabe.com/forum/threads/let-me-know-model-this-bike-is.140384/#post-957033 As can be seen it lost its seat and pedals/clips. If anyone has a restorable seat and a set of these pedals/clips I'm interested. Obviously the Duplex badge was added an no telling how it was originally badged but not Hawthorne either. The bike looks similar to the Hawthornes posted except the tubing sizes may be a little different. My main thing is to determine year and manufacturer. Any help is much appreciated. V/r Shawn
