Swan identification request

[Gaussian]

Here is a small self-filling Swan with a flexible #2 nib.  I know little else about this pen and would appreciate any information (model, manufacture date, etc).

This would likely be from the 1920s.  Beautiful mottled hard rubber pen, and with a hard rubber lever, which is particular to Mabie Todd.  I believe, but could be mistaken, that the rubber lever models were all Swan SM (Swan Minor), and for a size 2, it is SM2.  There would be other numbers indicating the color, short length, and trim, but I can't come up with these off the top of my head.

It is a beautiful pen and that nib is vey promising pen. Seems to be a very fine medium flex nib.

It shows the shape and what quality it has in writing. Need to have more work get into life.

Early 1920's before the US nibs had been replaced by UK manufactured Marrian nibs. Marrians were bought by Mabie Todd in 1920.
