Hopefully you'll track one down, but it is possible you'll need to configure the screen when you get it (unless you get one from LMBR). I say this because we also use various displays at our company, and quite often they need setting up for your particular use. That can be using resistors or bridging contacts. This 'tells' the screen what it is to display ie number of digits, decimal points/positions, characters etc. For example, resistor 12 is missing and the link bridged, plus some wire seems to bridge from R9 to somewhere else, so if you do get hold of one, check the back is identical...
