Thanks to Tinplate forum.
This item is on Ebay, link below, its a 9894 "Good Humor" reefer. I do not believe this is a Lionel produced item. If you have a Greenberg book handy please let me know if this car is listed as produced. I think its an RGS (sp?) as they produced replicas of cars Lionel did not make back in the day. The selled says it was produced in 2000, a long timenafter the MPC era. Thanks in advance.
