I can see there are a few variation collectors on the site, and I was going to ask this in one of the other topics but thought it would just get lost.
Apart from the few USA singles that were imported for sale here because of Vinyl shortage, plant problems or whatever.
Can Die cut Orange label singles be truly considered variations, after all there were companies around that punched there own for Jukebox use, and you can even buy you own hole cutter.
Don't get me wrong I buy them when I see them if condition is good and I know that the Elvis UK book doesn't list every variation. It's just a question that's bothered me for a while.
