Yes the bikes were made in Vitoria Spain by a company founded by a gentleman by the name of Don Luis Iriondo in 1948. They evidently built motorcycles also. I couldn't find much information online about the company or the bikes and they do seem to be quite rare in North America.
The mechs, shifters, crank and handlebars are original. A previous owner had added fenders, steel pedals, a rack, an adjustable stem and aero levers so that all came off along with a lot of weight. The wheels are Mavic Open 4 cd with Campagnolo high flange hubs, brakes are now Shimano Tourney cause they were the only centrepulls I had left. (The originals were Super Olympic and poor quality)
