    The best way to date these is the fork crown numbers. V/r Shawn

    I think the straight down tube was more of an early vs late kind of thing, because Huffman introduced the curved down tube into their line in 1938.
    They also introduced the Twin Flex that same year.
    It is odd, that any of the Twin Flex models were produced with a straight down tube, since that was going to be their flag ship model for 1938.
    But, for some reason, the first generation of the redesigned Twin Flex models had a straight down tube.

    They had both in 38. The Death bike is curved which would be the earliest frame. I think its more of a standard model or the deluxe badged models.

    Is the primered bike above yours? Is there another number under the H81500 likely either "1" or "2"? The 4 8 if on the primered bike would indicate April of 1938. I'll write more on my thoughts about this later as I really don't agree with the aforementioned theories on this. V/r Shawn

    I have a piece of literature that I can not attribute but is a mini history of Huffman from 1922-41. It talks about the introduction of the Twin Flex (TF) and says that after the recall of the original design aka "death bike" the TF was re-introduced in April of 1938 as a '39 model. It goes on to say "the model had a straight down tube for a month before it was changed to the double curved tube." This supports what Marty @cyclingday said about this being an early vs. late thing. The TF is an interesting model consisting of a lot of variety that is often overlooked. Such models as the tank camel back, economy TF--no tank, and a host of other things. This is probably a subject worthy of more study and a monograph at some point but I got other irons in the fire right now. V/r Shawn

    Weak... Factory literature or a collectors opinion page literature? Factory catalogs show straight bar frames into 1940. Twin Flex was a option, so most models could be provided from the factory as a Twin Flex.

    I agree John which is why I would like to collect as much info as possible. We have seen a lot of Huffman stuff that doesn't show up in any catalogs. Huffman's own dealer lit of the day essentially said they would option a bike to customer's desires and TF was an option on most bikes. So if someone has an original TF with a fork number of Jun '38 or later that would certainly dispel what I said earlier. V/r Shawn
