Well, there may be markings we have not yet determined to be a specific maker. As you can see from that book page, the catalog was from a distributor selling from various forges in Solingen. There may be guild marks (why I am stressing marks on the spine) but they are sometimes shown on the flat. A rose or other flower. There are so many blades as yet unidentified and more surfacing all the time. I have not forgotten and do hope to sit with books in the coming days but as the sword is a couple of hundred years old there shouldn't need to be a rush.
Two days isn't much of a wait and the one book plate was on the top of image files on my drives. One could invest in time reading about Solingen blade trade over the centuries beyond this thread.
You have prompted and enlisted others to do homework, or answer off the top of their heads and that's fine but my time has limitations as well. I am a little taken aback by this morning's prompt after my last post kind of answers your earlier question, now repeated.
Have I found the sword in books?
No.
Do I know the maker?
No.
How old is it?
In my opinion, not made for the ACW.
Cheers
