More mystery. Next to no info on Flex Craft or Flexcraft, looks like it wasn't too common.
On close examination I'm thinking the bow was never finished or used. Theres a rough edge on the side of the site window that was never final sanded. No marks from arrows or sign that a rest of any kind was ever attached. A finish was poorly applied to the handle that doesn't even cover completely. There are some dings to the edges of the limbs- but that could easy come from non-shooting related rough handling. Limbs straight, but on bracing obvious out of tiller (lower limb stiff). Also, I can get a fingernail to catch on the join between lams and riser here and there, and couple spots on the limbs, as if not enough glue used.
My theory: this was a factory seconds or reject that someone was gonna work on but never did. I'm guessing the semi-recurve limb shape like a BP Filly dates it maybe 1960-65 or so.
In any case, it is one of the most beautiful bows I have ever held. Time to turn this baby into a shooter. I plan to fill dings and gaps with super glue, radius the shelf, carefully sand the lwr limb belly into tiller, finish with Deft, and reinforce the tips with phenolic.
