The nib looks like a Waterman and the box says Made in France. My Waterman cartridges fit in it, but that's not much evidence.
I'll attach some photos I took tonight and perhaps someone here will see it and know whether it is made by Waterman or not.
Either way, I will continue to enjoy the way it writes - it is one of my favourites. So smooth.

I have two of them (dark blue and yellow). I do not think they are made by Waterman.
about harley davidson
and here too

Like, I have one of those! Mine is black. This pen is certainly not made by Waterman. It is, in fact, made by Stypen, although a Waterman converter fits in nicely. I know this, as there is a thread in the "Writing Instruments" forum, started by your truly, about this pen.

Yes, that particular model is by Stypen. Waterman made Harley-Davidson licensed pens after them. If I 'm not mistaken (and I could be), H-D pens are now being made by Retro 51.

If you do a search on Ebay for Waterman harley davidson fountain pens you will come up with several hits.

Here is the ebay item # for one of them: 350017488697. The metal case that the pen comes in says "powered by waterman"

I think Lewertowski would be the one to answer this mystery.

There are Harley-Davidson fountain pens made by Waterman, but they look like the Phileas/Kultur, not like the one shown above.
Look here: eBay

This one doesn't look like a Phileas and it's being advertised as Waterman.
Item number: 130087712653

Thanks!
Stypen, eh. I should look into what else this company has produced since this one works so well.
Off to read that other thread...

Mystery solved. Thanks again.

Yes it is a STYPEN, the WATERMAN as made 3 differents HARLEY DAVIDSON pens, the PHILEAS FREEWAY HARLEY-DAVIDSON, the HORIZON and the COMBUSTION but not this one, J.M.L.

I just purchased one of the models that resemble a Phileas. Somebody Help me!

regina martini offers some HD ballpoints.

I have always wondered the same thing ... I come up on quite a few of these on Ebay

I really don't think these are Waterman pens ...

Waterman's Harley pens are much different. They came in Waterman outer boxes with Waterman labels, and unusual cases.

Waterman's Harley's are:

The Racing series (Phileas-based body, comes in a tin box)
Three different finishes: Flags, Racing, Flames

The Horizon (Made to look like the kickstand, the case looks like the gas tank)
Available in orange, red, black, blue, chrome

The Combustion (comes in a case made like a headlight)
Available in black, steel blue/gray

On eBay, montgomerystationery sells the Waterman Harley pens. Other eBay sellers are selling them at super discounts. Yes, I have several.
