The Thin Model pens had been around for a couple of years before the introduction of the Snorkel versions, and there is almost no telling them apart from a small distance or with the caps on. Snorkel versions are very slighly longer to accomodate the mechanism, but in all other aspects the only give-away is the glimpse of the filler probe itself, lurking in the middle of the feed. As with the previous Touchdown versions, the shape of the body appears to have been a response to the Jet Age and its calls for sleekness.
Continuing a habit begun with in the Triumph era, Sheaffer made a lot of different “models” out of very small changes in trim and fittings. The TM Snorkels were highly modular items, with easily swapped points and caps, and it is the re-combination of these that gave the appearance of a vast number of lines. Unlike the Esterbrook Re-New Point plan, Sheaffer’s use of this modularity was kept in house; users were not encouraged to go poking around in the works of these pens any more than modern consumers are meant to rummage the guts of an MP3 player. As with the previous lines, this approach to different models means that in most of their dimensions are exactly the same, making an examination of the line rather less labour-intensive for me than was that for the Balances. The possible choices lie in the material (palladium-silver alloy or gold) and shape (traditional or Triumph) of the point, and in the material of the cap.
There is no accurate way to date these pens to a specific point in the model run. It may be said that those with a gold snorkel are early, but that is a very fuzzy distinction. Since there isn’t any particular cachet to “early” or “late”, it’s not a distinction which particularly matters, either. Similarly, later examples will appear with a section matching the colour of the barrel.
The external slimness of the styling combined with the internal complexity of the filler to seriously limit the ink capacity of this line. Whether this was considered at the time a great drawback does not appear, but I don’t suspect it was. People were used to the notion of regular refilling, after all, and a desk model I use in my regular employment has never run dry on a once-a-week filling regimen.
The Thin Model was swept out of Sheaffer’s line-up, more or less, by the introduction of the PFM. “More or less” because the body shape, if not the name, continued to appear in various Skripsert and lesser cartridge pens for some years to come.
|The Thin Model line are possibly the most resistant pens Sheaffer ever made in the area of posting the cap on the tail; have a look at this ad, and see how Vivian Vance has to screw it onto the back of the pen… if you can stand to watch such things. I seriously recommend against the attempt.
|For an extremely in-depth look at the various forms of TM Snorkel, its diverse colours, and an appreciation of the relative collectibility of the permutations, you may want to have a look at the Snorkel Guide at Vacumania.
Also, if you are desperate to hang a date on your Snorkel, you may be able to narrow the range based upon the colour– have a look through this article to discover the starting dates of some of the “secondary” colours
Production Run: 1952-1959 (The Special didn’t appear until 1955 or so)
Cost When New: See individual models below. Prices went up slightly mid-way through the run; I’ve used the 1955 catalogue’s prices (which is my most extensive price list for this era), and as the increase was mainly to address inflation it means that the modern equivalent (for which, try this calculator) remains more or less stable throughout.
- Plastic cap, open point: 14.1 cm long capped, 15.6 cm posted, 12.0 cm uncapped.
- Plastic cap, Triumph point: 14.1 cm long capped, 16.0 cm posted, 12.4 cm uncapped.
- Metal cap, open point: 13.9 cm long capped, 15.8 cm posted, 12.0 cm uncapped.
- Metal cap, Triumph point: 13.9 cm long capped, 16.1 cm posted, 12.4 cm uncapped (the odd results for “posted” are due to my unwillingness to gouge up barrels by firmly thrusting the cap onto the tail– see the note above).
- Desk model: Open point, 16.8 cm; Triumph point, 17.2 cm.
Point: See individual models below.
Filler: Snorkel, capacity approx. 0.8 ml.
Models in ascending order of cost:
Desk Models: There were three, the 5SKD which used the open 14k gold point, the 74SKD which mounted the two-toned open 14k point and the 121SKD which used the masked 14k triumph point. The cost depended upon which base they were mounted in, but it was never low. Colours were limited to black and brown, and of course the blind cap is specifically shaped to these models.
