1930's turkish-type flightbows

JNystrom:
This has been bothering me for a while... Has anyone built any of those 1930's turkish style flight bows, 110-130cm with only osage and sinew? I think many of you have seen these, but for a reminder you can check them out at Charles Grayson collection here. https://as-file.col.missouri.edu/fmi/webd/Grayson%20Objects For the search, use "flight" in describtion, "sinew" in material.
I notice there were many builders of these osage-sinew turkish style flight bows, such as E. Bud Pierson, Paul Berry, Curt Hill.

Normal measurements for this kind of bows were 112cm in length, 3.2cm wide, 1.0cm of thickness. If its possible to pull it off without horn, i'm in!
I'm just greatly surprised I haven't read anywhere someone trying these out.

avcase:
I haven’t built a sinew backed wood bow yet, but I look forward to follow your progress here. I think it would be interesting to try sinew backing with a stave that has lots of natural deflex in it. The sinew would pull this stave into reflex, putting the belly under tension when unbraced.  It might be possible to do this in such a way that the wood belly of the bow is under little or no stress when the bow is strung!

JNystrom:
Oh! Sinew backed bows are lot of fun, so definitely you should try it. Actually that osage recurve that I just posted here was deflexed in the handle, then sinew backed. Holds it's profile quite nicely, so it might actually be really understressed.

About these turkish bows made of sinew backed osage, i'm surprised this profile worked without horn. Wouldn't even come to my mind building a hornbow amount of reflex on wood-sinew bow. I guess osage is tough enough, and I think those bows had quite longer bending sections than a proper turkish one. I don't have any brace/draw picture of those bows, so hard to say for sure. I wish I had some old ye sylvan archer magazines... I found you could buy those magazines from internet for 40-80 dollars a piece.

PatM:
   People do seem really reluctant to pursue the design due to modern thoughts on sinew being slower and  hysteresis/breaking down of the wood.
  Back then they didn't stress too much over that.  They shot them and made another.

 I don't have access to Osage but  a short sinew backed hickory strip or bamboo  glued to an Ipe belly with spliced in static tips is a good substitute.
 
    Those old  bows routinely shot over 500 yards  and nobody gets close to that now despite knowing better.

  A guy on Paleoplanet did make a  true composite of this design with no reflex and it was pretty close to 500.

Badger:
Pat the bow you are talking about was in the overdraw classes. We are playing by different rules today, You seem to fail to see that in your comments.
