Ken..horns made by members of the Tansel family had a look and style all their own...the dates are like Guy says... Francis was the father...and John, Stark and Timothy were the sons, their work is similar enough to be confusing at first...once you've seen it, the charistic style and carving is unmistakably "Tansel"...checking out Shelby's articles (it was a 2 part series I think) in M.B. is definately the very best way to go...
John has captured very well the look of the originals.
