i agree with all that Trefor says, looks '80s to me. I never saw an Ernie Clements that was not a Falcon, that's the first I've seen under his own name and from this era. The rear spacing would also confirm that this is an '80s vintage (126mm for a 6-speed rear cluster?) and the seat post diameter (27.2mm?) might help determine if it's 531 Reynolds. Seems like it deserves some better components...
