I also bought the Opera Singers from Australia from Simon's Salvage and had them shipped. The figures are in a very poor and fragile state and it will be a huge task to restore them, but just about to start. The cabinet thankfully is metal and all sides bolted together, so that all came apart and flat packed (minus the glass, timber and plywood left behind). The power supply and record player and cams and everything else survived and will restore.
The figures were originally made in 1952 by Len Insull Jnr for Modern Enterprises and they cased them and made them coin op.
Modern Enterprises sold out to Ruffler and Walker within a couple of years, and R&W badged them up as their own, but the figures (Laughing Sailors, Cry Baby, Sidney Knows, etc) were all high quality Insull made.
