Roalco, Thanks for the info on the catalog offerings. Apparently, they did not call the boxlock a model name early on, just an A & D boxlock. Would you be willing to photocopy your catalog for me ? I'd be happy to pay you for your trouble. You are right about the balance of their guns; this one handles beautifully. I would love to see what a 20 ga. sidelock would feel like. Regards, Marcus
