Lagopus-
I don't have that book, it appears as if there's no digitized/searchable copy in the web either.
If you can scan that page and post it to this thread it would be great.
I do however have quite a few examples of 19th century text on the development of the metallic cartridge noting with illustrations a few variations on the pinfire system.
There was a guy here in the US who pulled a patent on the pinfire cartridge -- very recently. I think he had dreams of making money on the fantasy of a 'pinfire revival' - but the effort seems to have fizzled.
I've found that each gun and rifle I've had across my hands had it's own unique features - enough to the effect that in 'my perfect world' the cases and expendables for each have ended up being unique to each gun or rifle.
Is the invention you speak of the machined brass cases I've seen on the web featuring wooden toothpicks as support for the over-shot card, and the clever little threaded doo-hicky primer-pocket?
If so, it appears he's having fun with his pistol and shotgun ammunition endeavor. I wish him good success and welcome him out this way with one of his rifles. I'd be happy to get him out in our northern coastal timber for a couple days of deer-stalking.
If getting one of his rifles out here to the states would be too much trouble, I'd let him on to my Mahillon 16-bore or my Purdey 20-bore for the affair. They're both excellent running examples of the high grade light pinfire bore-rifle.
I'm sure we'd 'have a blast'!
Cheers
Tinker
