Help with my first Kamisori

Hello. I just purchased my first Kamisori and was wondering if someone could give me a little more information about it. It was listed as a Yamamasa. I know the kanji are pretty rough but can anyone make out the info from it ? Wondering what the date period it was from specifically. Any other info would be great too.

there is a member that can help you with that (Arsenico). there is a thread he started for that purpose. do a search under kanji help and it should get you there.

Thank you for your help. I found the thread.
