General Construction Notes for Allied Industries Ltd (Fisher & Paykel):
Murphy stereogram model prefix indicates radio bands - ie: SGA is Stereogram All-Wave, SGD is Stereogram Dual-Wave. SG means broadcast band only. Dashes and spaces seem to be used in some places while not others - ie: SG1387 is the same as SG 13-87
