Hum very strange - composed a reply posted it and it disappeared ! try again
I did a double take when I saw your string as I saw THIS!
listed on e-bay.com
and I knew that it hadn't finished ! Identical to your new acquisition!
I still have one of the miniature Safri weights 1 1/2" diameter and the
subject matter is identical to your new weight, ground is cobalt but the
base is fire polished. Looks as if he must have learnt a few things
between making my miniature and your new example
