wow,sorry my pic came out so huge guys,i'll work on that.But yes,looks to me like thats what it is,you can just make out the + sign on the bottom of yours,and check to see if it has 2 holes on the bottom where the studs would go,not all had them but pretty sure thats what you got there.
Darn I was going to say that, I came across one about 4 years ago cleaning out an electronics lab at a local school. I can't find it right now but that is what it is, I think. Cool!
