Looking for mac Plus info

With the talk in the past about the serial numbers for older Macs. I have a couple questions, that perhaps could be answered here, or point me in the right direction. A few years ago I picked up a old Plus to convert into an aquarium (I know, I know; but it was a fun idea). I had never quite seem a Plus like this before. It had a Sticker to denote it was a plus. It did not have printing or a platic label. It was simply a sticker. Now, Plus was stolen (why people stole it was beyond me), but I am still curious of the history that Mac may have had. I'd love to hear of any thoughts or such. I still have the keyboard and mouse from it, but I trashed the dot-matrix years ago. It was also an apple printer, but I was never able to id it. Wasn't and LQ or a first gen imagewriter. Very wide but not descript. Thoughts on that? Thanks for all. Chris
