Starting with 1918 the company went to a much smaller and cheaper "pocket" size catalogue, which included an inserted price list, but keeping the same "A FOX GETS THE GAME" cover format.
The earliest one I have is 36 pages and still includes the B-/BE-Grade gun, and is the first catalogue I have with the single-barrel trap guns in grades J, K, and L. The price list with this one is dated December 1st, 1919, and doesn't include the B-/BE-Grade, but does include the four grades of single-barrel trap guns -- J, K, L, and M.
The next version of this catalogue I have is 32 pages and has a price list dated February 1st, 1920.
The next of this type catalogue I have is 40 pages and includes the M-Grade single trap. This catalogue has a January 1st, 1923 dated price list that includes the HE-Grade Super-Fox in 12-gauge only, even though it is not pictured in the catalogue. There are two versions of the January 1st, 1923 price list -- one has the Super-Fox at $125 and the other has it at $100?!?
The final catalogue of this style is also 40 pages but includes the HE-Grade Super-Fox in 12- and 20-gauge, while its January 1st, 1924, dated price list still says 12-gauge only for the Super-Fox with the price still $100?!?
