Both poles on this ball, made by the North British Rubber Company, are marked "NB Rubber Co. Ltd." in a circle.  Inside the circle one pole is marked "Reg Design 590,217" which references a British registered design number that dates towards the end of 1911. Inside the circle on the other pole is "Patent 20778, 20/9/11" which references a British Patent dated Sept 20, 1911. 

The pattern of lines connected to large dimples across the entire surface of this ball is highly unusual.  This ball is a popular/desirable collectible in the world of early 20th century rubber core golf balls. 

For the record, this ball is the real deal and NOT one of the replicas or counterfeit examples  made in the UK. This ball still has the remains of some of its original paint and the gutta percha of its cover is clearly on display to demonstrate its authenticity.  The covers on all the other balls is not gutta percha.
