The blue frame looks to me like the road/track frame that westfield/columbia produced for many years. I think those had all 1" main frame tubes, and would have the shallow counterbore for the seatpost "shim", or "duster" as it's called. The fork was probably changed, and the fender cross brace having the boss added to accommodate caliper brakes at some point. I would research the westfield bike, and also the Indian "speedway" (cataloged) bike. Anything is possible with Indian. Witness the Indian/BSA track bike,as shown in this thread a few pages back. I am very fortunate to own one of those myself! Don't give up!!!
