Patrick: I hope you get that treatise by Rigby scanned- I'd sure love to see it. That brings to mind a question I've had on my mind for a while: Are there old technical association journals available digitally that contain articles of interest to old gun collectors? For example, is there a Britishicon engineering society publication dating back to the turn of the century that has pertinent material and can be accessed on-line? When I research a new project in my chosen field (geology) I drop by the local University library and can access all sorts of obscure stuff from all over the world.
