This is a 1940 Packard clock delete plate that may also be correct for 1939 Packard.  See the photos.

Nice original condition clock delete plate for 1940 Packard, maybe 1939 Packard as well. Check the photos, the bezel is scuffed in a place or two and has light corrosion on the inside edge next to the glass, easy restoration or use as-is. See the photos.

Diameter is 5 5/16th across the back side. 

Check my other auctions for more Lincoln Zephyr and Continental V12 parts. I combine shipping whenever possible.
