Well the description is certainly completely inaccurate, calling him a Lightweight. If it was a title defence in 38, which he won by KO, the only candidate would be Martinez, who was a southpaw. He doesn't look like Lewis to me either.
Hmm, that sure doesn’t look like arguably the best Lt Hvy to have existed Lewis, who I much admire, had a distinctive ‘cylindrical’ look to his trunk…there is no such body shape on display in this clip.
That's what I thought. If it has anything to do with a John Henry Lewis fight, it is as a film of the undercard. Even then, those guys don't look good enough to be on the undercard of a title bout.
That is John Henry Lewis and judging by the year I think the other guy is either Elmer Ray or Leonard Nebett.
