The first thing I found is that the well known John James Selby Walker b. around 1865 in Belton, Sunderland was initially apprenticed as a cabinet maker in 1881 but then transferred his skills to making cane fishing rods in Alnwick and is listed as a cane fishing rod maker in the next two census records, 1891 & 1901. When Hardy started making cane rods they are said to have hired good cabinet makers so there is the possibility that JJS Walker could have spent some time at Hardy.
JJS Walker started his own business in or around 1907. In 1911 his nephew James Alexander Walker was living with him and listed as an apprentice at a fishing rod works. James had lost his mother two years before and sadly lost his wife two years after their marriage in 1915. His father, also James Alexander was employed as an iron monger.
By 1911 JJS Walker was operating as JJS Walker & Co. Northern Rod & Reel Works, Alnwick, and had taken on Charles S Bampton, also born in Sunderland, who was a brass worker and former nautical instrument maker. Bampton was listed in the company's 1913 catalogue as being on charge of rod and net fittings. At the same time WH Dingley was shown as head of reel works having joined JJS Walker & Co from Hardys in 1911. Dingley was making the JJS Walker & Co reels and also supplying other companies with his own reels.
Dingley opened his own premises, the Climax reel works around 1913 but still continued to suppy JJS Walker & Co with reels. Some time before 1920 JJS Walker & Co became known as JJS Walker Bampton & Co.
James Alexander Walker went into business on his own and continued to trade as JA Walker & Co of Howick Street, Alnwick from around 1928 to 1938.
JJS Walker & Co probably commenced making reels after Dingley joined them in October 1911. The JJS Walker & Co reels would have been produced between the end of 1911 and before 1920 when they became JJS Walker Bampton & Co. Some of those early reels have markings stamped and also some reels had the name cast into the back during manufacture. I have seen two types of latch; the straight latch and the sliding brass button. They produced fly reels and casting reels and whilst information on reels is scarce there is an old Christies auction listing for:
THREE DINGLEY 4in., ALLOY REELS
All with twin ivorine handles and brake handles, caged drums, one marked Graham and Co., Inverness; another J.J.S. Walker & Co., the "Climax"; the third unmarked
