I know a little about the Mabie Todd brand, but haven't been able to find a single go-to page for information on their models over the years, and am wondering where this one fits in. I just cleaned it up and put a new sac in it, and it's a pretty nice little pen except for a pronounced tendency to nib creep. Might be better with a different ink (I'm using Namiki Blue), but never mind that now. Here's what it looks like.
On the flat end of the barrel, the number 54 is visible above the letters ETN. Along the barrel, their are three lines of text.
"Swan" Self Filling Pen
Mabie Todd & Co., New York,

The word "Eternal" also appears at right angles to the above, part way around the circumference of the barrel. The nib has the writing "Swan" Eternal 4, 14 Ct, Mab Todd & Co.
From the 1918 patent, I'm guessing that this is from the years of decline of the U.S. company, but it's a pretty nice looking pen. The only real manufacturing flaw I can find is with the cap. There are three breather holes, two of them are not punched out completely, and there are still nubs of plastic (celluloid) left in the middle.
This is the first lever filler I've seen without a springbar. The pressure bar hangs on a pivot from the lever. The lever has a hook on the other end that latches it into place when closed. It works quite well. I filled this from ink that had been transferred to a vial in order to get a rough measurement, and it took in a milliliter.
The nib writes a line somewhere on the border of fine and medium, it has no particular flex. It's writing a bit dry, I may try spreading the tines a little.
It's a fairly short pen; I have to post it to write with it comfortably.
Anyway, I'm curious to know about when this pen was made, and anything else interesting about it. And if somebody knows of a good reference page for Mabie Todd models, that would be good too.
