Paul, I will be letting go of some of my antique tool collection soon
(when I have time to take some digital photos). I have several old
style engraving balls--the type with the narrow neck, and a lot of
old gravers. These are all in excellent, usable condition, and I
have used several of them over the years. I looked for many years
trying to find one of these and when I finally did find one, I
seemed to find several. Over the years, I have accumulated 8 of
these, of various manufacturers and sizes. The round ball, currently
manufactured, is an adaptation of a die sinker's ball. The older
style engraver's ball is taller, and narrow at the top. Your hand
fits neatly around the neck, making it easy to turn. These are great
for lettering and scroll designs, but not as steady for setting
(hammering or pushing on them makes them tip).
Let me know if you're interested.
