This suggests that Dennis was still supplying F12s in 1961, although I have always been told that the F24/27/28 series were introduced a few years earlier.
Did Dennis produce both series alongside each other at this time? Or do I have my F20 introduction dates wrong?
588 BJF was on chassis no:4442, supplied 31/5/61, but chassis nos:4441/3 where supplied in 1959, this suggests this the last F12 was left hanging around. F24 started 1957.
