engine, radio outdrive manuals

[boatmandiver]

Anyone know where I can get hold of an engine manual for a 2.5 bmc diesel engine circa 1980. A radio manual for a Ratheon M56767 Telephone Radio, and last but not least a manual for an early Sonic outdrive, not sure of the model number but any info is better than none.

Thanks in advance
