My original post was to get some input on who the gunmaker was, as evidenced by his "signature" of NBF on the stock under the heel plate. I was sure somebody would chime in and mention they own a gun with the same markings and that it was definitely built by "X", in this case "Fashingbauer". RJH and Steve have posted their opinions, thanks guys; any more thoughts are welcome, but I guess we'll consider "possibly attributed to Fashingbauer" the judgment for now.
