This is the updated edition of Donald Dallas’s highly acclaimed book Boss & Co, Builders of Best Guns Only. This second edition brings the history of the firm up-to-date, with over 100 new photos, freshly researched material, new appendixes, and serial numbers to the present day. The new appendix on all the engravers who worked for Boss will prove of great interest to Boss owners, for now the engraver particular to each gun can be ascertained. By giving serial numbers up to the present day, guns can now be dated precisely and pairs long since parted can be re-united. This definitive history of Boss & Co was fully authorized by the firm.
