I've read that Waterman switched in about 1927 from "Clip Cap" to "Waterman's". However I'm not sure about patent date imprints on "Clip Caps" (they appear by the rivets).

I have seen "Clip Caps" that have the patent imprints, by mine is a "Clip Cap" with no patent imprints by the rivets. Is there some way of dating a cap based on whether the patent imprints appear or not?

Bump- any guesses?

The clips are a key to dating them. There are some old posts at Lion and Pen that get into this, but I haven't seen anywhere where someone lays is all out as to when the changes happen.

From what I recall - the first clips are from 1904-1905 and have "Patd. Pend." on them. I once saw one of these on ebay and didn't bid, because I figured it would go to big-time collectors - and the damn thing closed with one bid at 9.99 (not my bid) .

The next incarnation are clip-caps with a relatively straight profile, they have the first patent date from 1905 only, and would date roughly 1905-1910

The second incarnation has the 1905 and 1910 patents. This is, of course, the first clip one would find on a lever-filler.

The next incarnation has "clip-cap", is narrower, looses the patent date, and has a more curved profile. I think these date from 1923-1927, but don't quote me on that.

Then comes the "Waterman" clips, with I believe two variations, but again, don't quote me.

Hi John, that's just the sort of thing I was looking for. I figured the pen I had was in that vintage somewhere, but was just guessing really. At least I have a general idea now that corroborates my guess.

I really wish someone would do a primer on these pens the way sites like Richard Binder's did on the dating the Sheaffer Balance by color and clip. They made these Watermans for some years, but it's harder to date them than others like the Vacumatic, the 51, and the Balance.

For the whole clip lowdown see my question I posted to the Lion and Pen. I really wanted to narrow my 52 down datewise.

Interesting that this thread re-appeared today!

I actually just bought another 52 over the weekend-- this time one with the patents on the clip-cap. It's also the fatter clip cap. I wonder what the date on that would be-- perhaps an early one. The imprint is also fairly good on the body-- I don't think that has any patents in it though.

Some Pictures, any information is appreciated!

Dear Ray-Vigo;

I will be watching this thread intently. I just uncovered a Waterman hard rubber 52 with the very identical markings on the barrel but, it is appearing to be a very dark green color. Has "Reg US (Ideal)Faintly Pat Off then under it Fountainpen. The cap is missing it's clip.

The 52 has a heart in the nib, Waterman Ideal Reg US Pat Off

I certainly want to know the age of it, even though it is in an awful condition as it was put into an 'old cheese box.' I've dipped it since the lever is crudded in green and dare not tamper with it and leave it to professional pen doctors/restoring experts. But it does have that lolli-pop lever like yours. The 12 is straight/slim.

In the same box was a Swan, without a cap but--it also had a similar pattern rib like design and missing its cap. The Swan reads: Emblem of Swan - Swan - self-filling pen
Mabie, Todd Co. NY
Pat Jan 26, 04 Patents appliied for
Nib has the heart shape like the Waterman's nib but it reads: Edwards [emblem of a scolloped cross with 4 in it] Jennings.

And, found and unable to remove the cap is another Waterman that is brown and slim with a 12 on the end of the barrel's beehind. Cap Clip has the circle that looks like baseball stitch with Ideal inside of it, Reads: Cap Clip (Ideal) Pat Sept 26-05. I cannot see the nib and the cap is on real solid. I think ink has leaked and formed a seal. (Another case for a pen doctor) The barrel reads: Watermans (Ideal) Fountainpen
Pat. May 23, 1899 & Aug 4, 1903 (I looked at it hard with the best 9 power magnifying glass and it doesn't look like it is an 8 but--could be wrong).

So--I am being educated here

I like to know if I have something worthwhile restoring or selling.

Respectfully,
Maria

I believe the imprint on this one would date it after 1927, up till sometime in the 1930s. The Nib would be consistent with that time frame as well.




I don't know my Swans too well. David Moak is the person to ask (he is registered here as dlmoak), or check out his book Mabie in America.

The nib is a replacement - are you sure it says Jennings and not Jenkins? Edward Jenkins was a pen store and fountain pen repair shop in Baltimore that had nibs with Edward Jenkins and the cross you describe.



The clip-cap dates this one between 1905 (when the patent was approved for the clip) to 1910, when the 1910 patent was added to the clip (as you see in Rays pen above).

The barrel imprint does say Aug 4, 1903 - that was the date of the 2nd William Ferris Spoon feed that Waterman used from 1903 up till the 1930s. The imprint was used from 1903 through the mid-late 1920s, so it does not necessarily narrow the date down much.

They all sound like nice pens.
