This is more a broadcast item, but someone may have one sitting around gathering dust, or know where one is.
The model number is 451M1. It has a dual LED bargraph on the right hand side, and two selector knobs - one centre and one to the left of the front panel.
I have feelers out in most areas and have the usual (Ebay, TradeMe, pro audio forums etc) covered, so thought I'd post something here.
Any offers/suggestions welcomed.
