Anyone Remember Topp's (or Top's) Frozen Pizza?

This question is addressed to my friends in the upper Midwest and to servicemen stationed in Europe during the early 70's. When I was stationed there in the early 70's, the military commissary sold only two frozen pizzas. One was Chef Boy-Ar-Dee "Frozen Cheese Pizza". The other was Topp's (or Top's) Frozen Pepperoni Pizza. I developed a real taste for this spicy (at least to my mind, it was spicy) pizza since there was no American-style pizza to be had locally.
 
When I got out of the service, I made a real attempt to find some of this pepperoni pizza. During one summer vacation, I searched along Interstate 90 from Boston to Gary, Indiana (HaHa) and then jumped on Interstate 94 driving as far as Milwaukee. But I never found any ever again.
 
A recent reunion with some service buddies again brought up the subject of who was behind Topp's Pepperoni Pizza. My mind may now be playing tricks on me, but I remember the box stating it was made by Topp's Frozen Foods in Minnesota. If not Minnesota, I do recall it being an upper-midwestern state. I understand frozen pizza pies with meat were always more popular in the midwest. I just undertook an online search through corporation and trademark records, but am unable to locate any information. The problem is made more difficult because of the Topps Company, makers of trading cards and candy, and the defunct Topps Meat Co. (e-coli) which adds listings.
 
Unless this was a private label brand made exclusively for the military, I believe it would have also been sold in the Upper Midwest. Tony's was making frozen pies in Salina KS, but I don't think it was Tony's. Anyone remember Topp's?
