i have bought a copy and read about a third so far. Very well written, very insightful into 1860s hammer gun development and lots of original material.

David self-published this and is selling signed copies of the limited first edition. It is hard-back full-colour and nicely produced.

I recommend it to anyone interested in the era, the type of gun and English gun making history - especially the period covering the 1860s and 1870s.
