pan said:Interesting that the site lists BN3/4 as "THE" BN3, implying that it is the only one.
pan said:This mysterious car turned up several years ago, before the passing of Geoff Healey.
pan said:I understand he wasn't able to provide much information about it, but had earlier been a great help to Patrick Quinn about BN3/1.
pan said:Was BN3/4 perhaps, another one of BMC's failed experiments with little input from the Healey family?

You've got to love the exceptions...pan said:Reid, thanks for your detailed response to my post. I agree, "failed" was overstating the case, but BMC did so many experiments that never saw much of the light of day. Not much different to other large motor manufacturers, really.
John J, BN3/1 is a four (or two plus two) seater.
I have seen several references to the "economy" model Healey six as the BN5, but never any proof.
Personally, I have always doubted the existence of it. The Sprite, introduced in 1958 was designated AN5. The way the Austin Motor Co allocated model numbers is explained in most of the books: B indicates an engine of at least two litre capacity, N indicates a two seater and the numeric indicates the sequence. This formula was not strictly adhered to as the later models came along, but we do have a sort of logical sequence for a while: BN1, BN2, (BN3), BN4, AN5 (where A indicates a 1 litre motor), BN6.
I believe that the Jaguar C-Type started out as the Jaguar XK120C where the C stood for "Competition".
