Reference for identifying German military swords?

I took the plunge recently and purchased what is purportedly a Confederate naval boarding cutlass at a local gun show. I very much doubt it's a forgery as it's not a copy of anything particularly well known, like a M1841 USN boarding cutlass. It is apparently, as with the vast majority of Confederate naval arms, a European-sourced cutlass. It has a Bavarian-style 3-bar brass hilt with a waisted double-edged gladius-style blade that was all the rage that had been popularized by the French M1816 Foot Artillery sword (and later copied in the US in the M1832 artillery and M1841 naval swords). The hilt is peened, with a grooved hardwood grip, with no missing parts and it's nice and tight. If someone did forge this they went to a lot of trouble for not much money.

I did notice a bewildering array of German hilts while I was there. I gather this is due to the fact that Germany wasn't unified yet and each state had its own styles. I've been trying to find references online with largely no luck. I did find this site:

If you scroll down to "Tony without Kaiser's" second post you'll see he reproduced a couple of pages from a German book illustrating some of the hilt types you might find (the hilt on my cutlass is depicted in illustration #19). I saw others that weren't depicted, but I have no reason to doubt they're genuine. Does anyone know of a good reference for 19th century German swords?
