I am searching words "prewar bolo mauser" on yahoo.com (I collect some gun pictures), and found this picture posted by a Colorado dealer. Initially, I thought it's an air-soft from yahoo's thumb picture, but looking at details,,,, wait,,, no, it is a genuine one. Some of these guns are very well preserved in America.
