Hello. I have a Katana sword that was given to me by my grandfather about 15 years ago. He told me he swapped a German rifle for it in North Africa during WW2. It's been in storage. I finally found a knifemaker here who oiled it, took some pictures and told me it was indeed a Katana sword. Possibly pre WW1. I've attached some pictures. He was not familiar with inscription. Any other info would be appreciated regarding possible age, value, history, etc. I have the sheath as well. I'll try and look for some more pictures. Thank you.
