When the first Mabie Todd Swan SM 200/60 was introduced, in 1931, the advertisements highlighted a 'vulcanite flush fitting lever' as a major design frature. This continued in the 1934 update, this pen, until it ceased production around 1940.
The body of the pen is often currently described as also being constructed of vulcanite (hard rubber) but it is, in fact, black chased celluloid.
The 1934 advert for the SM200/60 describes it as having a Rhodium clip, presumably plated, although most sources describe it as being nickel plated. This clip is very bright and lustrous, perhaps the early pens were Rhodium plated and Nickel was used later on.
This pen has been conservatively restored and tested and is in excellent working order. The chasing is sharp and clear, as are and the numerous imprints on the pen. At the time Mabie Todd were very aware of the value of the Swan image and labelled every removable part, often more than once.
It is a decent sized pen, an impressive 16cm. length when posted. It is well balanced and has a very high quality, solid feel. The celluloid chasing feels good in the hand, it's quite a tactile item.
The 14Ct. Gold Swan number 2 nib delivers a medium line, perhaps a little on the fine side, with enough flex to add character to the writing.
