Full name needed for a point please.
Pick-up this one Experts!
Prince Miller LT1, about 1960
right or wrong?
Well, targhediferro might still get the point, but a bit of clarification.
This is a Prince Super-Miler from at least 1962 - the first year of the slanted quad headlights.
I think the model name was T431.
This was the one Prince vehicle that survived the Nissan buyout in 1966, since Nissan didn't have a medium-duty pickup in their lineup.
I believe this vehicle is:
A Prince Miler AT 431 Model Year 1964.
Correct, though I have the full name as Prince Miler LIAT 431, but you are are close enough.
