I've just done a quick count of the rods listed in the 1938 Allcocks Anglers Guide and there are over 100 covering bottom fishing, spinning, fly and sea. The same blanks but with different reel fittings, rings and whipping patterns are given different numbers or names and many of them are available in several different lengths resulting in several hundred different rods.
Most just have numbers, but there are quite a few with names too that are not on the list yet:

There may be more in the dealers catalogues which were more comprehensive than the guides and I'm sure there were new rods in the 50s and 60s that are not in the earlier catalogues, but someone else can list those, my fingers are starting to hurt
