Need help identifying this unusual three tab shingle

Can anyone help me identify this three tab shingle? The shingle measures 39 1/4" x 13 1/2". No identifying marks on the back of the shingle. I’ve checked the major manufacturer’s websites, but can’t find anything close to this. Thanks! http://img696.imageshack.us/img696/2731/shingle.jpg

They almost look like the IKO skyline kind,maybe these are the starter course for them?..i dunno…

It kinda looks like a old Globe shingle.
