Oh, brother. Okay lets continue. The only problem is they only cover the English patents and do not fully cover the French, German, Belgium and the other countries that have developed the breech loading sidelock. Hopefully, the book or books mentioned by Wildcattle, when translated, will cover those countrys development as well. A more complete study of even one of those countries would be beneficial as to which maker called what pin a peg or an axle or a pin.
