Just my dirty and unsolicited 2 cents:
The Art Deco styling of that 41-46 is going to create a stronger sense of "brand recognition" than the 61. The 60s trucks are cool, too. I used to own a 66 that I wish I still had.
But something about that 41-46 waterfall grill makes it a universal head-turner and conversation starter. Your son's pizza truck is one of the coolest on this site.
