Re: Ink Stamp on Patent Plates

Changing the patent plate to add space for paint and trim (and dropping selling dealer and date of sale) occurred partway into the 22nd series but probably after November 1947 production. From my own observations except for 1954 and later, paint and trim codes were always stamped in ink.

Just when they stopped stamping the key numbers on the backside of the plate is something that it would be nice to pin down. Anyone have any sightings of key codes on the reverse later than 1936?
