Bannerman Catalogue this is a great reference, I read once that there were no mistakes in the descriptions, they were selling these items when most were fairly new, great way to identify some of those items your not sure about, there have been reprints but the pages are not in order + and missing alot of the items, some items in this book have an angled line through them, meaning they were sold, this one is missing the cover, the pages are yellowed, + one must be careful when looking through it, as it will flake + pages will tear if not handled gently, if stored properly this one should last another 100 years or more.
