What were the different patterns of Collier, and what was the timeline of their development and production? Today I'm discussing this with Professor Ben Nicholson, author of Headstamp's most recent book, "Clockwork Basilisk". We will start with the original clockwork Colliers, then the standardized run of flintlock manually-operated revolvers, and then the different types of percussions examples, both factory and conversion.
