I have to dig up this thread, yesterday night I found by a eBay search this sword of the same type, see the seller pictures. The seller accepted my offer!
Now I wonder if there are any new insights about this swords.
The scabbard shows like some others the snake, the coins (some are missing), the bucket man but also a centipede but the scabbard isn't so much longer as the blade. And when the pictures don't feint it shows some good age overall.
