The Thin Model was essentially a pure design exercise. The big internal change had happened in 1949, but that left the outside of the pen looking essentially the same as those sold since the end of the Second World War. This could hardly suit the forward-looking nature of the time, and so a much more slender profile was offered. It still looked like a linear descendant of the Balance, but where that line drew inspiration from Zeppelins, the Thin Model was looking in the direction of jet propulsion.
Production Run: 1950-1951.
Cost When New: See individual models below. Prices went up slightly mid-way through the run; I’m sticking with the initial price, as the increase mainly means that the modern equivalent remains more or less stable throughout; for modern values, try this calculator.
Size: Plastic caps- 13.4 cm long capped, 15.7 cm posted, 11.8 cm uncapped. Metal caps (including all-metal body)- 13.3 cm long capped, 15.7 cm posted, 11.8 cm uncapped (the results for “posted” are extra-long due to my unwillingness to gouge up barrels by firmly thrusting the cap onto the tail– see the note above). Admiral and Craftsman, which follow previous body styles more closely are 12.7 cm long capped, 14.9 cm posted, 11.1 cm uncapped
Point: See individual models below.
Filler: Touchdown, capacity approx. 0.8 ml.
Models in ascending order of cost:
Craftsman: Open 14k gold (marked 33), plastic cap. Cost when new, $3.75. The Craftsman had not been brought into the previous Touchdown line, and it had languished through 1949 with a lever for filling. The body shape is actually more in line with the previous “fat” models, but the inner mechanism is the TM style with a narrower sac.
Admiral: Open 14k gold point (platium masked “Feathertouch”), plastic cap. Cost when new $5.00. Like the Craftsman, the Admiral had not seen the new filler mechanism until the appearance of the Thin Model.
