So, I could use your help identifying a pen, again. It's another Sheaffer - the nib is labelled -79- Lifetime - U. S. Pat Off. - Made in USA 14K. The body and cap are striated brown and the white dot is on the end of the cap. The clip is quite plain, and cap band is medium-sized (which is causing me some trouble on the identification). It's obviously a vacuum-fil - I'm a bit afraid to try and fill it because I'm sure it's been a long time and I assume the components are degraded. I haven't dipped it to try writing with it.
I've found some pens on-line that would suggest this maybe a Crest Triumph model - but the ones I found had the white dot above the clip - so I thought this might be a pre-world war II model.
As usual, I appreciate your expert help and advice.
