1930s track bike with diamond tubing

 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.

 Pop Brennan for Expert Sales Repair Work.

 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.

1908 Caminade Track Bicycle

very cool track racer.
chater lea headset, Caminade chainring. New Departure rear hub,
Persons saddle, John Bull Toe Clips, and what looks like Torrington pedals.
the very interesting feature is the square tubing for the chainstays.
the crimped seatstays at the dropouts to make it more rigid.
the unique seat cluster, it uses the 2 clamps, one is the traditional seat binder bolt-
the other is the early seatclamp that tightens with a conical sleeve, and a threaded unit and a nut. Tightening the nut compresses the sleeve to then hold the seatpost.
I'm not sure why it used both.
the headlugs look like early BSA lugs, no keyholes.
The bike has been restored, not sure what is original and what has been replaced over the past 100 years, but still a very interesting bike.
This bike was on display at the International Cycling History Conference,\
and was on loan from US cycling Hall of Fame Museum.
