Do all the 340's have small "s" stamps in front of the "P" or just the T/A's?

Quote:

Also notice the smaller font "S" that is stamped ahead of the "P" in the assembly stamping.

*I have 3 original production line 340's, all 1970 casting dates, 2 more 340 warranty replacement blocks, one cast dated in 70, and one in 73, none have the "T".
