Titania bicycle
 

Hello,
Does anyone have any information on a TITANIA bicycle which was sold in Paris from about 1900 onwards please ?
I say sold because because I don't know if the bicycles were actually manufactured by the company TITANIA. or were assembled from components manufactured by others, There was also a motorcycle TITANIA brand offered by the same company, according to a poster, on Google - showing a bicycle.
I wonder if the frames were supplied by one of the many St. Etienne companies of the time ?
Any information would be greatly appreciated.

Can anyone identify the chainwheel with little "snibs" on the rim [ not Durkopp ] and also the brake calipers please ?
