sought-after ! Lot of 20 1930s Practisor Berghman Co. Putting Trap

This is a lot of 20 1930s/1940s Early prototype/release putting traps. This are so extremely hard to find. Made by Berghman Co. This is what once was a patent pending product that eventually became the Practisor Hole In One Putting Trap. There's the original red design, and green. The flags included that go on top of the trap are wrapped in 1930s telephone book paper, the numbers and how it looks aligned with that era assuming they were wrapped but the company in early production. The finished design already is exceptionally hard to find so this, this is a one of a kind find. There's 13 brand new in box greens, 4 brand new reds, and 3 boxes that are new as well but the flags fell out. Any paint chipping or wear in box is from age and storage. It's pristine condition given its timing and definitely a piece of gold history. An remarkable find. I have individual listings but trying to sell this as a lot.
