11/16 Henkotsu Kamisori

Attachment 115547 Attachment 115546
Hi all. Can anyone tell me about this razor? It was listed on our Classified forum today by member mainaman and bought just now by me. I'm thrilled to have it as I have been looking for one for awhile now. My family background is Japanese but I know nothing about kamisoris. I'm glad to find this one from a trusted member because my knowledge about these is so limited.
Can anyone here provide additional information about this razor? How old is it? Any information about the maker or really any information at all would be greatly appreciated.
Thanks, all.
