Hagstrom guitars were manufactured in Sweden, and sold worldwide by different distributors. In the United States, the distributor (at this point) was Merson, who were soon to merge with Unichord, under the umbrella of Gulf + Western. The 1966 Hagstrom guitars and basses with the world's fastest playing neck catalog was printed by Merson for the US market. It was just eight pages long - shorter than the Hagstrom guitars and basses move people that followed later in the same year, but containing the same basic product range of eight electric guitars, five acoustics (including one electro-acoustic) and five bass guitars. This A4 catalog (12" x 9") has been produced in just two colors, grey scale images with purple highlights.
The catalog itself is entitled "Hagstrom guitars and basses with the world's fastest playing neck" - and the cover image and much of page 2 go on to reinforce this claim, detailing the Hagstrom "H" expander-stretcher truss rod, and the thin, fast-playing neck.
United States Hagstrom distributors allocated alternate model designations from Hagstrom themselves and Selmer (UK and commonwealth distributor). It's not clear why Merson named solid bodies as F-series instruments, but Selmer had been selling these guitars branded as Futurama (i.e. Futurama II). This theory is given further weight by the fact that the European names of the semi-acoustic models (Viking and Concord bass) are replaced in the US by V-1/V-2 and C-1/C-2. A few models did keep the same names - notably the Coronado bass and Impala six string guitar.
