Great thread!
I've had/have many of these new and previously unreleased 45's on my website over the years and the right ones fly out!
I've sold upwards of 100 copies and above of the better releases and most labels only make 500 copies, so it doesn't take long for them to be deleted as they sell across the world from other dealers/websites etc. Occasionally on massive sellers, they'll do a repress (Cookin' on three burners, Oliver Cheatham, Patrick Henry etc) but in general most labels seem happy enough to sell the initial press, then get on with the next release.
So i guess many of these will be the rarities of the future with already quite a few examples around of new 45's becoming hard to find in the last 10 years or so?
Keep 'em coming
