farmall 450 serial no ?

SIL is looking at a nice 450 with a wide front and loader serial says it's a 57. What does the S at the end denote? Haven't seen it other than a video of it running and several pictures, will go sat and check it out, looks to be all original and not beat up at all. Not sure if its an IH wf or not yet.

From my research on my 400 I learned that the s means that it should have a TA and independent pto. Does it have those?

believe it does, has the ta lever on left and pto lever on right. would the pto lever be in a different place if not live, Dad had 2 SMTAs one was ta delete but both were live pto he also had a 450D so I am some what familiar with them although that was over 40 years ago. When I left home, he had one of the SMTAs, 450, JD4430 and a 4020.
Thanks for the info.
