Sorry chaps, I only just noticed this string on the forum. According to my records which are freely available on the Members' Side of the ACOC Model Directory on the Website, there were 29 convertibles and 52 Fastbacks including CF 81. There is also the Booth Brothers' Prototype 429 4 Seat Coupe which could also be included in the 428 register. From the 81 428's listed by the factory, I have managed to find 69 of the original cars, of which one has been converted into an Aceca Special, and 4 into Cobras, leaving I believe 64 428 Fruas which are known to exist. There may be future barn finds so I live in hope that some gaps may yet be filled. Andy.
