Sunn was doing mix and match during that period, so there isn't one specific cabinet for it. Most people used the 215S, or the 215M (same cabinet, better drivers). I prefer the 115S. Similar design, with only one 15. Stack two, similar performance, easier to cart around. Also available at the time were the 118S, 118H (folded horn cabinet), 215H (folded horn cabinet with two fifteens), and some people even used more guitar-oriented cabinets like the 312S.
