I've always wondered how much the different gun makers got together, maybe Saturday night at a local tavern. Certainly, if they lived close enough to each other - but we have to remember that 30 miles or so distance would take at least 5 or 6 hours travel by horse. So a whole day taken up by going and coming,
I can see how, if living in the same vicinity - within 5 or 10 miles - there might be some visiting from time to time. Perhaps looking for a good piece of stock wood, or a lock already built. Further than that, however, was probably a very rare occurrence.
