might be the 18" model for cocktail monitors, the pots not being on a separate "remote" board is the tell for me (they would sit under the tube because they stay stationary, they don't flip out like Midway ones). it's been many years since I've done anything with one of those. my most recent experience was with Sharp XM-1801s last year, and putting together a Sanyo AZZ that Paul Juray fixed for us.
