Mannyrock- welcome to the "Plug Door" club...beardog 49, Dave Ripp and I have some pictures of other similar boxcars in earlier posts in this thread. I agree, Lionel made these in many variations, often for a particular set or commercial customer. They are normally not expensive and fun to collect. You have a great start! However once the bug bites...I will warn you that some of the more unusual ones, like the Town House Appliances and the Kaybee toys (7031 & 7032) pictured in beardog49's post above will usually go for more than $8. Oh yea, and if you look at Dave Ripp's post above, you will see that there are at least 4 variations of the "Baby Ruth" car. Happy hunting!!
