The later ones had chrome flashes on front wings and doors with 'Singer' above, didnt make that many, about 9000 i think. When you consider the Jowett Javelin from 1948 to 53 they made 25,000 of which several hundred still survive.
In 1955 Singer bought out the Hunter S, an economy version with painted grille, no mascot, fog lamps, chrome strip or arm rest, never seen that variant. I think the bonnet was grp.
