If it was a restamp it was likely done when the car was restored. Pre-1994. But other than the K which is suspect I think the rest of the stamp looks correct. Am I way off?
Everything but the "K" looks correct, or at least believable. The "K" is defintely not sharp-faced as the other stampings, had to be after the original stamping was produced, or substituted. It is in alignment with the balance of the stamping, correct size, it just looks goofy. Need to strip the paint and look at the deck surface to see if it's been monkeyed with - either way, somebody messed it up to the point where it can't really be trusted anymore. And it will be difficult to proove validity.
