Bayonets of Japan, Raymond C Labar

I don't really have another book to compare it to so as far as I'm concerned it's the best Japanese bayonet book out there. Lot of great photos, layout could be better. Feels like reading a large print version which in a few more years I may appreciate more. Sometimes it is a little awkward to find specific smaller markings as they may be on a separate page but they are there. Been out of print for a while so getting more expensive. Fly Shack of all places still has them in stock, signed by the author. Not much on dates but serial number ranges are there which is impressive.
