[Price Check?] Golfcraft Putter used by Cary Middlecoff in U.S. Open victory

[z123]

Hi,

I have a Golfcraft Troon Combo Frank Johnston Model putter that Cary Middlecoff used in one of his victories at the U.S. Open. I'm trying to get a gauge on how much it is worth. The problem is, Middlecoff won the U.S. Open twice and, so far, I've been unable to pinpoint when the club was made, so I'm not 100% sure in which victory this club was used. Once search yielded a result that said the club was made "~1960," so, as of right now, I think it's more likely that he used it in 1956 rather than 1949, but I would like to be sure. 

If anyone is knowledgable enough to give me some information on the year of production or the potential value of the club, that would be great. Thank you.

(As of yet, this club is not for sale. I'm just trying to gather information.)

Here are some pictures for reference.
