That chainring screams Huffy to me as well BUT, with the reardropout screw adjusters and the fact the rear and front rim do not match, im thinking it was a skiptooth to standard conversion. The chainguard, fork crowns and rest of the bike, minus the chainring, don't scream Huffy to me. In fact, the chainring and frame lines make me think late 40's if not early 50's and dare I say a Hawthorne, or perhaps an early Huffman.
