OK,what's with the estimable Mr. Brown, the trip to the Paris Exhibition, Mr. Vernier, and wrapping the scale around a threaded caliper? I had a very early B&S example, gave it to a deserving historian....BLJHBGood find. I'd love to build the James Watt micrometer if there were drawings available. And talk about history, there's a thread going on over at PM on the history of the Palmer micrometer, the first patented micrometer in the style we use today. I'd love to find one of these at a flea market.
