What's the casting date on the water pump?

Re: Water pump #s
 

One is 57 and I have one with a 60 on it.

Re: Water pump #s
 

Casting date should look something like this....for example: C217, March 21st of 67, or it could be 77. Is there a letter visible?

The only letter is a D on the front right.
