This is essentially a revival of the original Triumph TR3-based Ambro built by William Aldrich-Ames (Bill Ames) and Dewey Brohaugh at Rochester MN between 1961 & 1964. One complete car and around 40 bodies were produced in this period. The body had strong Maserati Birdcage and Lister influences and some body panels were molded on Don Skogmo's Maserati T-61. The body molds were accidentally destroyed during production of an Ambro body.
Jump three decades and the story of the car is resurrected by Bill Bonadio, working with Bill Ames in the early 1990s, made another set of molds and these bodies were produced under the name Dio Tipo 61.
Fast forward to 2007 when the rights to the Ambro name and production of the bodies were acquired by A.R.E. (Alexander Racing Enterprises).
ARE now produces a new and improved chassis frame with a Triumph TR3-TR4A donor car desirable for final assembly of the rolling chassis.
The Ambro story is, of course, much more interesting and involved than the brief information I've provided.
The puzzle car is I believe the first car built by Alexander Racing Enterprises on a new Triumph frame and is currently being campaigned by it's present owner.
