anyone ever see a marking like this before on a carb?

[resq302]

Figured I would pass this on as I just came across this on a virgin carter AVS 4 bbl carb, dated J9 carb number 4934S for our 70 challenger convertible. The carb still had the brass screws that held the throttle plates to the throttle shafts and everywhere else still had the swedged or squashed over ends of the threads so they cuold not back out. It appears to be a rubber ink stamping on the back side of the top plate for the carburetor from our 70 challenger which has a SPO date of Sept. 28, 1969. The stamp either appears to be I94 or 194. Possibly a date code which the carb was assembled?

Love to hear your imput on this who might have come across this as this is a new one to me.
