vintage Waterman Ideal Junior USA Fountain Pen w 14K Gold Canada Nib 1S

Here's a nice looking old fountain pen with a 14k gold nib. I believe this dates to the 30s or 40s.
The body of the pen is stamped Waterman's Ideal, Reg US Pat Off, Made in Usa, Junior. The nib is marked Waterman's Ideal 14K Canada 1S. I can't seem to find any info on the 1S nib but it looks like it's in great shape. The pen itself is in nice condition with some tiny scratches but no cracks, breaks or damage. The clip is engraved Watermans and has some scratches on the surface but is tight. The cap also screws on tight. Afraid I don't know anything about the internals of the pen but the lever seems like it's in good condition also.
The pen measure 4 3/4" long when capped and about 6"
If I can give any additional info please let me know. Thanks!
