I bought several at hamfests over the last few years. None were used, all were new-old stock from failed 220 trunking systems. I still have one BNIB on the shelf next to a BSR220 for a one of these days project. Still need to spot or build an antenna. Also have a 5 channel combiner.
They are out there.
