Identification help. Is this a #12?

[geoffmartin]

Hi,

I recently acquired this pen and I'm trying to figure out whether it is a #12 or not.

As can be seen in the photo, the nib that was on it when it arrived was a Heimdal that was completely wrecked. (I live in Denmark, so this is not an unusual name to see on a nib). There is no visible imprint on the cap.

Now I've trying to figure out whether the rest of the pen is an old copy of a Parker 12, or if it's the real thing.

Any opinions or advice are welcome!

Thanks

Seems that I might wind up answering my own question.

It looks like there is a Paul E. Wirt that looks extremely similar to this one as well. There's a photo of an example on this page:
