46 may have been the last year for hand crank??..... but the AD grille, if I remember correctly, had an indention down on the bottom bar.....not sure why?
I have the crank and the balancer pulley with hand crank provisions on my '51 3100.
Haven't used it - motor is in storage, but I've turned it over a few times with the fan blade.
I have a nice little scar on the point of my chin from hand-cranking my Model A ages ago. Held on a little too tight (even though I used the correct grip - no thumb wrap around) when it kicked back and hit my chin on the radiator cap. Things went black for just a second.
But I'm OK now now now.
