just picked up a 1970 CTW block
 

...and got a kick out of this casting error... it doesn't look like it was ground off, but rather likely from the "P" getting filled in before being cast, likely not the only one, anyone ever seen this before?... hah. Just curious.

The Perfect block for a high strung car buddy :)

Someone in the foundry having fun.

Its also missing the "F", if they could have made the i to y, would've been perfect.

Even though quite the prankster

That's just funny, you should show Alan Colvin - he's seen more unique blocks than most!!
