Key chain from either Trophy Pontiac in Bayonne, NJ or Kellogg Pontiac in NYC
 

I'm trying to locate an early '60's correct key chain from either of the above dealerships. My '63 Bonneville was originally delivered to Trophy Pontiac in Bayonne, NJ, and my dad purchased her in January of '65 from either Kellogg Pontiac in NYC (where we lived at the time) or another dealership - though his original set of keys was on a Kellogg Pontiac key chain.

I still have the Kellogg Pontiac key chain (black plastic disk with the stylized "P" engraved on the back and a clear insert on the obverse with the dealership info under that). It has what we used to call a "snake" chain from the plastic disk to the keyring itself (with a clasp). The clear insert and dealer info has long since gone the way of all things.

Anyway, these couple dealerships seem to be difficult to track down. A web search reveals that Kellogg Pontiac apparently went out of business in the mid-70's, and the assets apparently sold to a similarly-named dealership which relocated to Mount Vernon, NY. From there, the trail has gone rather cold for the moment.

Thanks!
