This is fairly typical of the low-end makers of the 1920s and ’30s; an attractive body, with a very simple filler and hardware that is competently stamped out and plated with almost nothing at all. This specific model is clearly meant to fool the casual observer into thinking that the guy whose pocket it rests in has gone out and spent a pile of money on a spiffy Sheaffer Balance, which is what I base my dating upon; no such thing to emulate before a certain date, no one will be impressed after a later one.
The other thing I note about this pen is that despite the rather primitive nature of its point, it writes rather well. I suspect this has something to do with the degree of competition between the low-end buyer’s money in that period; since everyone who used a pen had a sense of what a halfway decent one should feel like, makers dipping too far below that benchmark in search of a really cheap pen (whether for volume of sales or enhanced profits) found it a counterproductive exercise.
I’ve recently had a note from someone else who’s had one of these apart that the dimensions of the piston seal are essentially, or at least sufficiently, the same as those on a Monoject 3 ml syringe. That’s a much easier repair than the fashioning of a seal from stock which I’ve done, and I’m happy to pass along the tip.
