" Austin Healey (BN 4 ? )with steel disc wheels and hub caps which is a rare sight today "
Ken H, yes would say BN4, as definitely 100 -Six, has the crease in the bonnet [ hood in the USA ] and those steel wheels would be very rare in the USA.

Interesting timing of your post, as BMC BOY [ Ross Cammick ] called in to today and delivered a 1;18 scale Model that his nephew didn't want anymore, Not a Healey 100 though, but a model of my other great sports car, a Triumph TR4 in French/Powder Blue. A good find for the collection.
Ross still has his BN7, the two seater version of the first 3000, but arrived in the daily driver a Honda HRV. No photos to show.
