Well, "it looks very much like an Eagle Pommel Dyer Type" and then "Looks similar" are much like I mentioned the way many look at swords. On a scale of ten, the only real visual similarities are the grip color and that it is an eagle pommel. Truly, all components of the two are completely different.
Jen's sword grip has obviously (imo) been replaced. I had posted examples that are true siblings of Jen's sword and background for them.
Browse through those folders on my drive and you may see the visual differences and similarities to the Solingen swords. Sharing my images is fine with me but it does invite my commenting on them and differing with your opinion, if only to clarify what they represent. Perhaps I was just startled to see the Dyer type posted out of context. Look to the German, Berger, misc and unsorted folders for examples of Jen's sword.
There are many good books for American swords and for the eagles, here are some of the required reading if interested in eagle pommel swords.

Two out of print and highly sought selling at original retail. He must have come across some boxes of them. Get them while they last.

There are other such as Bezdek's books valuable for makers lists but individual sword info sparse.
Another companion primer to Peterson's for early American sword is Neumann's Swords and Blades of the American Revolution

Some are better than others for the later swords. The Medicus collection is a good flash card deck. Those are some of the books I go to for eagle information. An amount of older information needs amendment.
