Please help ID vintage Waterman with a safety nib

[Kikay]

Please help identify this vintage Waterman safety nib pen.

 

What I know so far:

1 It’s a Waterman safety nib (much like the Montblanc Bohemes)
2 Julia Gusano said it’s from the 1920s.
3 It has an eyedropper filling system.
4 The silver has a 935 grade.
5 It’s smol.

Looks like a Waterman 442 1/2v or 442 1/2v BABY, which stands for (4) sterling silver, (42) safety with #2 nib, (1/2v or BABY) smaller size. Pattern looks to be the hand engraved vine, and eyedropper from 1910-1920 is accurate.

Thank you for sharing this information. I checked under the bottom finial where I’ve read a few find the numbers. It says “42 1/2V”. So it is a 442 1/2V! Your direction is much appreciated!
