vintage relish plate server, silver lazy susan turntable w/ insert crystal dish

1960s vintage silver plated lazy susan relish server with heavy crystal clear glass insert (divided plate about 11 1/2" in diameter) The silver turntable is large and heavy (it measures about 15" across the rim).

This is in very good condition, I'm not sure it was ever used. The silver is tarnished, but doesn't show any particular wear to the silver plate. The glass liner looks excellent, no chips, cracks or scratching.
