I am trying to identify the model name for this Sheaffer pen. I have two that are all but identical. One has the price code "1500" while the other, slightly smaller model has "1250". Both are lever-fillers, have gold-toned threads on a black barrel, white dot on the tail end of the barrel, Triumph Lifetime nib, and a matte "satin" style metal cap with a gold-toned clip and cap band. I believe these pens are from the 1940s and may be among the early Triumph pens, but I don't know if they have a specific name, such as Vigilant, Statesman, Valiant, etc. Both pens are spectacular writers!
Any help is greatly appreciated. Thank you!
