I know nothing about the marvellous Luna Ciclles brand
Based on next-to-no-evidence, I believe it is a Portuguese brand, possibly manufactured in the city of Agueda. Agueda used to be home to a large number of bicycle and bicycle component manufacturers.
A number of people have speculated about the spelling of 'Ciclles'. It has been suggested that this is a Catalan spelling or a Basque spelling or a spelling from some other more obscure Iberian language, but I can find no evidence for any of this.
I can certainly say that I bought the particular Luna Ciclles derailleur in this collection from a Portuguese person.
