Unknown builder with incorrect fork. It does have Pop Brennan decal on the headtube, but we do not believe it was built by him. It may have been worked on or repaired by him. The lugs are finely filed, rather uncommon from this time period. The rear triangle is built with diamond seat and chain stays, I have never seen a bike with this treatment. Unique CCM steel cotter-less cranks, wood wheels, and early Persons saddle. Any help in identifying????

Thinly filed lugwork.

CCM cotterless cranks. rare design with a triangle taper, rather than the later standardized square taper. BSA chainring. 

CCM crankset from Mike Barry’s Blog

Extremely long stem, with lamp bracket attached.

Early Persons racing saddle with saddle support attached.

 A brake as an afterthought. It clamps on the seatstays, and does not require the brake bridge to be drilled.

New Departure rear track hub.
