After Bianchi, the second oldest still existing bicycle company in Italy is Olympia. The company was founded in 1893 by Borghi and Guerra in Milan. Guerra later left the company making Carlo Borghi the sole proprietor. They have made some very nice bikes over the years, but are generally overlooked by most collectors.
My first quality bike in the mid-70's was an Olympia that looked very
much like the one being offered for sale on French ebay:

I have dealt with the seller in the past and while he is perhaps not the most knowledgeable, he seems to be very fair.
The translation of his description is: OLYMPIA CARLO BORGHI bike
