Well...the fork is a teens Michigan City (excelsior) fork.....but the frame has some traits that look interesting. Fork is not Davis. Can we get more pictures of the rear fender stays and where the lower(tank bar) enters the seat post? Also if the frame is Davis it will have the unique stamped serial number on the bottom bracket.
The bicycle has Excelsior features and more. The truss fork with the forged crown looks Excelsior.
Never mind — (see the other duplicate thread, with somewhat better pictures, under those poor lighting conditions).
Not sure what the “P. C. & A. S. Co.” might stand for, but I thought that a CABE member may have recently offered a badge, “Serl” (or Perl?) — so marked on eBay.
Also, there is a badge so marked on a “show us your badges...” thread — 2nd post, “Mohawk” badge.
Probably not associated with that other bicycle manufacturer located in the Mohawk valley and on the Mohawk River, (not by the higher Cohoes Falls, but the smaller falls).
Most people may associate “A.S.” bicycles with the famous AlbertSpaulding — but his was more a Chicago concern.
