John,

Web searching came across this forum discussion about the Snap On FV71M ratchet:

https://www.garagejournal.com/forum/threads/snap-on-fv71m-ratchet-rebuild-question.351506/

Seems there is some thinking the the "V" indicates may have been a military issue tool and possible from the '60s???

Also mentions a currently available Snap On rebuild kit to restore the ratchet if worn out (RKRA380).

I also found what is noted as a Snap On "Date" code chart that may be of help in determining the date of this ratchet (maybe - maybe not)???

I didn't see anything looking like a date code in your pictures.

Helpful - Yes/No/Maybe So???
