Identify This Sheaffer Model (No Cap) ?

[Paul-in-SF]

I acquired this cheaply as something to practice repairs on. The nib says: "Sheaffer;s Reg, U.S. Pat. Off. Made in U.S.A. 14K" It is a wraparound nib that looks like a Lifetime but it doesn't say that. The barrel imprint says "W.A. Sheaffer Pen Co. Fort Madison, Iowa, U.S.A. Made in U.S.A."

 

It appears to be a vac filler, and the second photo shows what you see with the barrel off. The third photo shows what you see when you pull out the plunger (that part stays inside the barrel when the barrel is unscrewed. It doesn't take up water, so I am assuming the filler system needs repair; or else I'm trying to do it wrong.

 

Due to its compact size I presume it is a Tuckaway, but I think there were different models of Tuckaways and I don't know which one this is.

any chance this might be an old style touch down? - it looks similar. The failure to suck up might be due to a failed O ring seal - some of these sacs can be thin - always possible there's a pin hole somewhere.

Looks like a touchdown Tuckaway (valiant, sentinel, crest).

Possibly. Now that I know what to look for, I was able to find examples of Touchdown fillers that looked like this, but those pens appeared to be longer. However, I did find a picture of a Tuckaway model called Sentinel that appeared to be about this size. Also the nib and barrel imprints were the same as this one Thanks for the tip, I believe you've solved it. (posted before I read doggle2's post)

 

eta: based on the section, I'm going to say it's a Sentinel rather than a Valiant or Crest. I imagine they all get repaired the same way in any case.

By the way, just wondering if the 7-digit number on the nib has any meaning that would help identify the model?

[PaulS]

some of Sheaffer's patent Nos. are seven digit jobs - alternatively it could be a date ……….. Lifetime warranties ended up covering only the nib, apparently.

How does the No. read, and are there any dots or commas in the No.?

Touchdown Tuckaway. Any of the later Triumph Tucky caps will fit the pen.

It's very worn, Under 60x magnification I get 3057351 and I can't see any punctuation.
