Schematic and replacement meter for Orban 412a ?

EDIT: THE SCHEMATICS IN THE MANUAL!!  :

ftp://www.orban.com

Anyone have a schematic for the Orban 412a compressor. I found the manual here which is very comprehensive. (and contains some humor!)

Also i have a few units with blown edgewise GR meters.
There marked Emico, but thats it.
There moving coil and i plugged in a 1mA Sifam and it seamed to behave its self

Anyone have a source. I've googled but no luck so far.

The cut-out size is 46mm x 20mm

thanks

I bought a couple of meters direct from Orban a couple of years ago. I think they were $12 each.
