Nos. 2 and 4 are Packards I think. Probably straddle my own in years, but the V shaped rad is typical. After the number plate fell off mine I painted a thick piece of rubber with the number on and tied it round the rad. On my way to court in Stoke for an accident that wasn’t my fault (obviously) I was stopped and given a ticket because it was against the law to have anything other than a flat plate. I pleaded in vain all those sports cars that had them painted over a curved bonnet, all to no avail.
