Mystery solved and started!

[M ELEY]

I sent detailed pictures off to a museum in Germany who finally confirmed that this sword isn't a Jaeger hanger. The gentleman found a near identical French grenadier sword, matching the details of my hilt. I had originally thought about the brass-hilted grenadier swords, but the typical variety had a different pattern to the hilt. It took this professor digging through the museum archives to find one similar. I am perfectly happy with the outcome and am just glad to have some clarification.

Now, the grenadier swords all had curved blades, so it seems mine is similar, but not an exact fit. Going back to my original argument, this still could be a naval/maritime hanger. The brass hilted naval swords of the 1780-1800 period were Plain Janes like this. The spear-point, double edged blade fits the bill. French merchantmen, privateers and such were very prevalent during this period.
