Old lapidary equipment knowledge wanted.

Anyone know how to date an old Star Diamond Industries Tumbler model number TU 6&6 w/ Serial number 1856?

How about Scott Murray HY-POL grit in tin cans manufactured by Don Bobo's Lapidary Products? How old is this stuff and do they still sell it somewhere? Are the old tins worth anything or should they be collected?

I have an old HY-POL tumbler also, anyone know of Don Bobo's Lapidary shop?

This padded "bucket seat" has become one of my favorite field trip tools. The swiveling seat snaps right onto most 5 gallon plastic buckets. It's a great product at a great price!
