Ive got this. Its pretty interesting. Very similar to Stanley Kubricks film about Walter Cartier.

I did not figure it was really a lost film.TCM has most of the RKOfilms
in their vaults.I have just never seen it.
Prizefighter inspired Stanley Kubrick to make DAY OF THE FIGHT,
and that was released in 1951(based on his own earlier photo essay of Cartier that appeared in the January.18. 1949
in LOOK magazine.
