Some of you provided very helpful information!!! I am truly grateful to you.
It is always nice to find pens with a personal history. This Sheaffer desk pen is from late 1920s-early 1930s. You may want to check whether there is an accompanying desk pen base.
Can you unscrew the broken part of the taper/tail? The taper was connected to the barrel by a metal threaded stem so it should be removable (but it can be difficult to unscrew so do not use too much force).
Below is a Sheaffer advertisement from 1926 showing the Jade green Sheaffer desk pen:
Joss, so far I haven't found the pen base, but there are still a few boxes to go through. I'm hopeful, but realistic.
If I wind up having to replace the base, what specifically should I look for? You mentioned my pen is from the late 20s - early 30s. I'm happy with that information, while also wondering if there's a way to narrow the time frame of its production?
After posting, I realized I hadn't posted a picture of the feed; perhaps there's another angle that would help some of you experts close in on the date.
Yes :-) the (broken) taper rather easily unscrews. I was able to do that even before posting here, and now I understand why I couldn't figure out what the heck I was looking at. In my limited experience I should have been looking at part of the filling system. It didn't look like anything I'd ever seen in person or online. Thank you for clearing that right up!
EDIT to add: I'm not able to pull the section, nib, or feed however. Is the section friction fit or screwed in? There's a small (maybe 1 mm) gap between the section and the barrel where I think someone began to take them apart; they are stuck pretty tight though, and I don't want to force anything. Thanks again!!
Oh, wow! What a cool ad!! Do you happen to have an original of this? Finding one is now on my wish list. Thank you for sharing it. Everything that adds to the story of this pen is important - it was my grandparents and it helps to complete the story. Some of you get that.
apologies in advance for jumping into someone else's thread, but just to show one in the flesh and with all its parts of tail and base marble etc. intact,
PaulS - No hard feelings, and my first thought was that you really were just wanting to show me a different but kinda similar pen.....
OP, in response to the other questions in your post, it is an easy repair job. Your pen will require a new sac (a couple of bucks) and a new taper, which should not be too difficult (or expensive) to source. I'll check to see if I have a taper in my parts box; perhaps others here will do the same.
Daniel, this is the best news!!! Knowing that a repair should not be too problematic. It's very kind of you to offer to look for a taper among your spare parts. If you have one, I'll gladly pay you for your trouble and its value.
By "sourcing the repair," do you mean the parts or finding a reputable, conscientious repair person? I'm interested in the latter if you know of someone. Perhaps it's easy, but I'd rather my first personal experience be with one that I'm not sentimental about.
I agree that the plastic plunger does make it appear to fill by pushing downward like a Vacumatic, but this one does pull right out to reveal a s/s rod, and so I've assumed it's a standard Sheaffer Balance Vac-fill which sucks up directly into the barrel. Will post a picture showing the withdrawn steel rod later. The terminals on most steel rods belong to these Vac-fil models have a different appearance from this pen, so maybe this one is very unusual as you suggest.
These early models not remotely within my comfort zone, and I see Marshall & Oldfield devote several pages to service and dismantling such pens, so I've stayed well away from tinkering with this pen - difficulties appear to abound, and I don't need to use the pen presently.
Of course if I have this all wrong do please shout.
PaulS, and then you proceeded to jump right on in with unrelated pictures and questions. Again, no hard feelings, but please begin your own post. Our pens are very different: filling systems, nibs, era, etc.; the only similarities are shape, that they are desk pens, and PERHAPS the same manufacturer, but even that doesn't appear to be crystal. If you want photos and discussions of various models of desk pens to be included in your post, by all means propose it that; way I'll jump in and share pics and what I've learned about this one. Thank you for understanding.
It's a standard vac-fil, it just doesn't have a blind cap or taper attached.
Thank you, Roger W, and forgive my having to ask...which pen are you referring to? Mine has a lever, which I think is always(?) usually(?) referred to as a lever-fill, but I'm still learning. Thank you for clarifying for me.
