Not an outrageous price these days for a book with such a small target audience.

Mass market paperbacks are $15 and their hard cover equivalents are $28 and up. I've switched to a Kindle for new & recent books partly due to cost and mostly that I am running out of room to keep all my actual books. I expect more and more books will no longer be published in paper leaving only coffee table style books or books with lots of illustrations and pictures like the 'British Gunmakers'.

I have become addicted to English hammered shotguns to the detriment of my wallet.
