thanx arno,

you have diligently answered all of my questions. i was starting to wonder whether someone
had gone to the trouble of making a replica! after one he probably would have given up as it
would not have been profitable unlike some models that a readily copied !

best wishes for the forthcoming festivities ...

: stands for hour and T stands for tachy, calculators were slow
: sellers at the end of the lifecycle hence the additional model,

: available for the black, similar to Autavias, Carreras, Monacos,
: Verona, Monzas all was a little mixed those days, I also own a
