Yet another piece of history demystified by Dr. Drew (w/lots of talented help). The next time I pick up a double from this period, I'll be looking for this article to help me understand just what the previously unknowable barrel marks actually mean.

When you consider how the mists of time have obscured most of this information until now, this is a fairly remarkable achievement.
