G'Day Anne-Marie,

If I might suggest a source for you to check; Model Airplane News or RCM would have issues available from that era. Could you not look through the advertisements from Top Flite (or for that matter any modeller here with old issues might be able to find something?

Chances are, the model number was included somewhere in the ads. It's even possible that the mags have archived/microfiched ad information that could contain what you need.

Oh well no prize but I thought this might help
