The selection is still peculiar: for example, the book on the Chinese Mausers, Arming the Dragon, is a reprint Dolf Goldsmith's 90ies work on Chinese imports. It's dreadfully outdated and working on insanely sketchy grounds (even the author admits so). Of course, a reprint is cheap, but we don't live in the 90ies anymore and despite issues research and sources on chink weapons have leapt forward in a massive manner.
Or the fact that the same author of Arming the Dragon wrote some excellent books on the Maxim and the Browning. Why not reprint those? They're rare and starting to get insanely expensive.
Of course, his business, his books, his choice. But at times I grind my teeth in having to hunt for used copies in some boomer collection and seeing absolute vanity projects thrown out just because. It's like he doesn't want my money, nor he does need to because parasocials.
