Stainless Steel 3 bowl sink with 18" drainboards, waste drain valves with twist handles in beautiful wood cabinet. Based on the dimensions I'm pretty sure the sink is a SSP/Elkay 3C16X20-2-18X. You can see the specs here: https://www.elkay.com/products/details/3C16X20-2-18X.
See photos for condition. The sink retails for around $2k, plus the faucet, waste drain valves, and cabinet. Make an appropriate offer. You haul.
