That's what it looks like. Sometimes they made the can flat and cut the top and bottom off to make a sign or a patch for something. The can took a donor to make it round again. It is a good thing to do if you find a really really rare can and want to make it somewhat right. Some guys are really good at making the cans look original by not using a donor can but most of the time they are shorter because the original can was cut.
