There were two rather rare guests for a therapy on my workbench. One is a Fidelity Research FR-66s with B-60 Elevation Base in excellent condition. The second guest is not quite as rare, however, this SME 3012-RG has never been assembled and 40 years only stored!? The bearings were refurbished, the internal wiring was renewed and a bronze cutting edge bearing Mk3 was mounted.
