Picked up a "Koban" razor on the bay hoping that it will look good in-person...
I really liked the spine work, blade etching and the metal details on the scales.
Now, the scales seems like they could be past-expiration and the seller did mention that the metal decoration is coming off them a bit (there is even a piece of tape there to secure them...) - but..if the blade is sound I wonder if maybe I could have it all re-scaled...and have the old metal decoration transferred to the new scales... Crazier things must have been done

I tried to find any information on the "Koban" brand but didn't come up with anything from online.
There is a marking on the back of the tang as well (see photo below) with something-something "Bros" maybe?

Any help in figuring out what this is would be greatly appreciated
