I do believe this is the first twisted metal bow I have seen. I found only one ad for it, so I wonder how well, if at all, it sold. Couldn't find a patent either.
Very unusual in that you can shoot it not only left or right handed, but also, front or back and available only in 3 weights of 25, 30 or 35 pounds in either recurve or straight limb configuration. I wonder how that front-back thing works with the recurve?
From Archery magazine, May 1949.
Since we can't see the whole bow, we are left to guess at the look of it. I expect it was a single bar of aluminum that was twisted so that the wide sides of the bar lined up in the handle and then on the other side of the twist became the back and belly of the limbs.
Another guess would be that only the straight limbed version was reversible.
On the con's side, metals, especially aluminum, have a lower strength to weight ratio than wood. Thus wood bows of good design will always be faster and smoother than metal bows. On the pro's side metal bows don't "let down" in the heat, and don't break with use as wood bows are prone to do.
History tells us that the con's of metal bows won out.
Interesting design. The twist must be to give the handle area some rigidity.
Lots of innovation came out of the post WW2 era. Not all of it was viable, like this^^
