Antique Wood Shaft--Very Unusual Anti-Vacuum Patent Golf Club

Offered is an unusual Anti-Vacuum Patent club.In researching this club,I found an example in a 1980's U.K. sale catalog. That club was umarked. This club is stamped on the crown but is very weak. The only thing I can makeout is the last name of the maker,which is Tait.The unusual part of this club are the two scoops at the rear of the crown. This was obviously done to promote sales of the club,with the theory being it would change the aerodynamics of the club when being swung.Hence the name Anti-Vacuum.The club is 43 inches long,has a straight shaft and the grip appears to be original.It shows minimal use and is in very good condition A unique and unusual club for the patent club collection. See all photos. More patent clubs in my other listings.My old eyes could not read the crown stamp until I saw the zoom pictures. I see it is Archie Tait,who was a U.K. clubmaker. I'm still trying to decipher the rest. If you can read it,let me know.  Thanks
