Chromodora Front Indicators

[Tim Ray]

I have got a pair of Chromodora Front Indicators, with orange lens. I bought them having been advised they were for Series 2 /3 Fulvias, but they do not fit.
They appear not to be handed and both bodies are marked Chromodora 4180291 and 1.100.18.
The lens have lots of markings including STAR  and LAXIA.
Does anyone have any Chromodora data, or know where I might find it to identify these parts. Chromodora in Italy couldn't help, as they only hold info. on cycle parts these days.
A friend suggested they may fit the Fiat 850 Coupé and Spider, but I cannot confirm this. Not too many examples of these models in this part of rural France.
I bought them as "new old stock" and they are in excellent condition.
They are just gathering dust at the moment and they might just be of use to someone.
Any help or suggestion very welcome.
Regards
Tim
