Jack -
I don't have an opinion about the bow, as I have not yet seen good enough photographs to be able to know for sure what the bow really is. At this point, for me, any statement would be a speculative guess, not an opinion. I usually don't like to make guesses.
I don't know if it is the "real deal" or not. In the past, when apparently uncommon items have surfaced and just a little information is presented about them, I've been both pleasantly surprised and gravely disappointed, especially if I rolled the dice on an on-line auction... As a certified appraiser, over the years, I have had many clients who have been disappointed to learn that an item they paid a lot of money for is not authentic and that its actual value is only a fraction of what they paid for it.
Usually, good quality close up photographs will tell the story of the item. And if the photographs are posted on a public forum such as this one, many collectors of that particular type of item usually give their input, the relative information eventually comes out, and an accurate answer to the question about the authenticity of the item becomes obvious to nearly everyone.
If anyone has any additional photographs, it would be great to post them.
Doc - I remember seeing photograph(s) of your 1966, but I don't know where for sure... I'll see if I can find them...
