A Niblick from days gone by...
I think it says "WARRANTED" rather than WARRAN LTD"
You can see the origin of the word "blade" to describe a simple forged club. Mostly what we call "blades" are a "muscle back" design i.e. they have some additional weight behind the ball rather than being a flat piece of metal.
Although it says "8", as mentioned above, it would have been more like a wedge and probably the most lofted club in the bag.
When you factor in what the balls were like and how precisely you would have to hit the ball for it to go anywhere it makes you realise just how amazing some of the scoring was when Jones, Hagen, Sarazen etc were managing to shoot in the 60's round championship courses.
Love the story about J Douglas Edgar. What character! Would make a great piece in the magazine.
