This handle style does not appear in both the Wagner and Griswold chapters in the BB or RB. I looked through hundreds of old ebay sold items on worthpoint.com, and only four of them had this handle style. Of those, only one was an exact match. Where this one is 1168, the rest were 1169 or a single digit size number. So... I don't know what that amounts to. Recast? Rare? I'm very curious to know how old this is. Thanks!
