This one-off Miura Spyder was built in 1968 by Bertone. The car never had any form of top or side windows. The factory had little money to pursue the development of this car and so it never went into production.
The open top roadster was first shown at the 1968 Brussels Salon where its unveiling even surprised Ferruccio Lamborghini. The original paint applied to the original Miura Spyder was light blue metallic. The rocker panel and air scope were painted white. After the car was returned to the factory in Sant'Agatha it languished there for several years until sold to the International Lead and Zinc Research Organization (ILZRO) who commissioned the conversion as a showpiece for their products.
ILZRO is the corporate research and development activity of the lead and zinc industry worldwide which had, by 1966, developed new alloys, coating system, plating systems, techniques for use of our metals by the automotive industry which needed a dramatic "vehicle" to introduce these developments to a broad segment of the automotive industry, not simply to the few people with whom our industry had worked but to the industry at large domestically and internationally.
The Spyder was rebuilt in 1969 with Bertone's help replacing many parts with Zinc where possible: carburator velocity stacks, inlet manifolds, exhaust system, radiator, oil sump, water pump housing, all water lines, bumpers, grill, steering wheel, switches, door handles, shift lever, hand brake and taillights. Lead was also used as insulation under the floor and in the doors. The interior retrimed in one color, the car was repainted dark metallic green and used for publicity. In this guise the car was renamed 'ILZRO ZN75' and toured the world.
After completion of all of its shows, the car was returned to the U.S. and subsequently purchased by Shrade F. Radtke, Executive Vice President of ILZRO. After presentation the car was restored to operating condition for use as a road car. Mr. Radtke finally donated to the Boston Museum of Transportation in February of 1981.
The car went through several owner's hands before it was eventually sold to property tycoon Adam Gordon. The Spyder has now been completely restored back to its very original 1968 Brussels Salon configuration by Gary Bobileff with the assistance of Bertone SpA.
The Miura Spyder exists as the only genuine open top Miura, and is the only works one-off Miura in existence, easily making it the most valuable Miura extant.
I am not a natural flatterer, I like to think that I "tell it like it is", politely I hope. So when I tell you that I am very impressed by the contents of your website, it is just not English politeness. I of course love the subject matter but you deal with it in an energetic and respectful manner. I am overwhelmed by the research that has gone into compiling the list of coachbuilders/bodybuilders for Europe and North America. I have never heard of the vast majority of them.
Congratulations on an excellent website.
