First of all, kudos on figuring out a way to scan the negative with a standard scanner (at least, that's what I'm understanding you did). I'm sure others here would like to hear how you managed to do so. For myself, I messed aroudn with it for a while, and finally broke down and bought an Epson 4990 scanner to handle the medium format and larger negatives that I have.

Any chance you could crop/enlarge one of the patches on the uniform sleeves? That might help narrow down an ID.

The only team that I am seeing with a City/Mascot combination of K/P (which may be an incorrect assumption) around that time is the Knoxville Pioneers (1921-24). Unfortunately I don't have any photo references for them to compare to. Having grown up in Knoxville though, I would be very interested to know if anyone can confirm or preclude that as a possiblity.

Later matching City/Mascot combos include the Keokuk (Iowa) Pirates (1947-49), Kingston (New York) Ponies (1947), and Kingston (Ontario) Ponies (1946-51), though as Leon noted, I wouldn't guess those based on the clothing styles.
