I buy and sell alot of clubs, I was rummaging through my collection of blades and found this, can’t find any information anywhere on the net. Can anyone help?
Will leave a proper assessment to @Crow, but to me the John Letters iron is immediately interesting as for decades they were a, if not the, club of choice for the top British players - in fact I think on occasions in times past the full UK&I Ryder Cup team would play John Letters.
It's a club that was produced for the Professional Golfers Co-operative Association Ltd which was formed to enable club professionals to buy as a collective and so get a better price from manufacturers.
There were showrooms/warehouses in London, Manchester, Glasgow and Birmingham.
Your club was one of several designs that were produced specifically for the PGCA, in this instance by John Letters.
As you can imagine, it's not particularly rare or valuable but is a nice collectible.
Date-wise I'd guess 1960s.
