Jeweling metals, need info

[mklotz]

Not that it will be much use to you in Italy, but my aforementioned box of four grades of lapping compound came from:

Gerald Kerr Associates
8999 W. Pleasant Valley Road
Cleveland, Ohio 44130

(I Googled them but couldn't find any current listings; they're probably long gone.)

It contained cannisters of grade 120, 220, 280, 500 (order coarsest to finest) grit. I can remember using the 220 and 280 grit on some jeweling jobs.
