I have a Stanley 78 plane iron (and plane). The logo on the iron is "Stanley Rule and Level Co" in a semicircle (a bit more than a semicircle, actually). Inside the circle is the following: "
Jan 30, 83
Nov 18, 84
Reisd (or Peisd, or Relsd or Pelsd)
Oct 23, 88
It's hard to see the word that I have several options on. Could it be RELSD to mean "released"? And if so, why would they put that on the iron? What would "released" mean? I can read the rest of the trademark clearly but that word is faint.
[Added note: No patent dates on the body of the plane, and I can't find any casting marks on the body or the cap.]
