Sorry, but right over the road a piece from me is a full time cooper ... and his barn is chock-a-block full of handsome barrels and other nifty "containers." The trade's been in the family for generations and Dad & Sons now operate it very successfully, thank you very much!

As for real blacksmiths, there's one working at Strawbery Banke in Portsmouth with his hammer, anvil, and all that, not to mention a great pair of shoulders!
