Who made my Pacific Coast Rubber Company Heavy Service?

[hoofhearted]

Thanks Patric,

I just skimmed through the 30 pages of Davis bicycles.
Post #426 on page 22 has an ad that shows a 1916 Yale Roadster that looks like my bike, same fork crown. There is also another but different Heavy Service bike on the same page. It looks like some years had a two piece crank. Do you think my bike might have had a two piece or a one piece crank? Can the frame be fitted with either?
Thanks,
Chris

Chris ... you made a valuable discovery ... see ''RED'' content
in 1916 document, below ...

And peep this DAYTON RACER ...

Bricycle purchased this unit from MsRock ...

^^^ I purchased the CRANK - ONLY from Bri ... It will be placed in
my H-D Military Model (tall frame) ... will be using a H-D ring.

Foto supplied by Balloontyre (Ivo) ... authentic WWl battlefield image.

NOW ... to really cornfuze the issue ... YALE often used the 4-Circle cloverleaf pattern ... As Did the Davis NATIONAL. .. However ... at some time, Davis introduced The Y-A-L-E ring ... don't know when .... yet.
