There are several facts to be considered first of all.
1 is that this feed is rarely seen on the Tuckaways. I've seen more than a few over the years and this is the only one like it I've seen. Of course, that's only anicdotal.
Embedded error here is the assumption that because the feed may be relatively scarce, it therefore was only produced after the patent was granted, or that it was only produced at the end of the production or marketing life of the series 1 Tuckaway. The conclusion drawn is unsupportable.

Sheaffer certainly wanted the pen to succeed and probably added it (the new feed) to the end of the product run in an effort to increase sales of existing but unsold pens. I'm quite sure that this internal feed is interchangable with the externally finned variety. One would assume this because they never advertised the feed at all, probably because they knew the new model was on the horizon.
This assertion is internally contradictory. You claim (without any specific evidence) that Sheaffer "probably" added the "new feed" at the end of the product run (an unestablished claim) "in an effort to increase sales" of the model -- yet you also state that Sheaffer "never advertised the feed at all". If Sheaffer were so concerned with increasing sales, why would they go to the trouble of tooling up to manufacture an improved component, yet never advertise it?
I again point out that this dubious line of reasoning relies on the unsupported assertion that the feed was not introduced until after the patent was granted -- a completely unsubstantiated claim.

You'll remember from your Macro Economics class (if a business major) that a company makes money from manufactoring processes that are intensely short. Sheaffer would have tooled up for the early Tuckaway and made all the ones they thought they could sell. This pen didn't sell well at all so I seriously doubt they continued to make them into the following year. Their money is made by getting the product out and then tooling up for something else.
So are you claiming that Sheaffer made all the series 1 Tuckaways in one intensely short production run, presumably in 1939 or early 1940? And, by your reasoning, that Sheaffer in general made, in one intensely short production run "all the ones they thought they could sell" of all their models, then kept them in inventory for whatever number of years they anticipated the model's lifetime was to be?
Do you have any documentary evidence that this was the way Sheaffer production was performed?
QUOTE
Fred advised me (Fred started repairing and selling Pens in 1945, at a store begun by his grandfather c. 1922) that Sheaffer reps stated they retooled for new models in September so that they would be available for Christmas.
How does this bear on your claim that Sheaffer waited until their feed patent was actually granted before they began production of that feed?
Here you state that Sheaffer retooled for new models in September; previously, you stated that Sheaffer
ended their production runs in September after two months of production. Can you clarify?
QUOTE
Your point about registering for Patents is a strong one. But then Companies were issued many patents they either never used or sat on until the time was right so I suppose neither of us can say when they would have begun production.
That was my point -- you stated that Sheaffer wouldn't have begun production until after the patent was granted. I appreciate that you now acknowledge that you can't say when production of the feed would have begun, and, thus, that the reasoning underlying your original claim that the feed was produced after May but before September of the same year is erroneous.
It is no less likely that the feed in question was, in fact, the
first style feed used in the Tuckaway, and that it proved unsatisfactory, so it was supplanted by the more common version.
