Here’s a fender tag decoder.
Early Valiant Barracuda Club - Fender Tags
Looks like a nice car with great upgrades like the Commando engine parts and disc brakes with a dual master cylinder.
It does NOT appear to be an original Formula S.
I can’t tell but it may have originally had AC.
It’s has the upgrades needed to make it useable in today’s traffic and could make someone a nice unique daily driver.
The difficulty is the value on these is especially low but are trending up but not a lot. So be careful- do not spend too much on this as you can be underwater financially. I think the only time to purchase one of these is when you really love it and intend to keep it for many years as they are totally unprofitable financially but remember the alternative is to drive one of today’s bland-mobiles.
