Hi Greg – welcome to the forum.
When Stone and Tirri are mentioned, why not also mention Egerton, Lord of Tatton? As his book ‘Indian and Oriental Armour’ could also be of interest to you. You can get a reprint very cheap, so do yourself a favour – buy it now before it is sold out
.
Robert Elgood has edited a book and written several, all worth having, and don’t jump the fence where it is lowest, read the notes as well, and you will be surprised of all the pieces of information he gives – if you are interested in the subject that is.
There are, of course, many more books, and according to you wallet and interests, I would be surprised, if the members of the forum could not fill a bookcase or two within a very short time.
