From Richard Great Western expert....hey Phil...if there was a Fauber crank with threaded cups, the housing was smaller and it had notches. Some export and contract bikes were press-in cups and non-Fauber stamped. ALL bikes that GW made after 1921 were non-Fauber with no notches,bigger BB housing and press-in cups..... Hope all is well with you
I was directed to Gendron bicycles recently, and discovered that some of those bikes had the scooped BB with 3-notch threaded cups. (Also, I believe I've found an application of my odd truss fork). So, were bicycle makers who used an external source, such as Fauber, for parts such as bottom brackets and cranks, more likely to go out of business earlier?
Not sure about the sourcing out of parts by mfgs. caused closings. Iver Johnson made most the parts for the bicycles they sold.They went under right around ww2. After ww1 quite a few bicycle mfgs.closed after making munitions for gov. and great Depression set in. Shelby,Colson,Columbia,D.P.Harris, and a few others struggled through. Dayton ,Davis went under then came back.
