Yes, interesting one this. Manship says acetate only and Record Collector only 2 know copies. The label, which I recall was white, black and orange ( not 100% on this) was designed by John Bollen originally from Skipton/Earby area ( he is pictured in Blues and Soul on the Dave visit to the Wheel along with Franny O'Brien and Lesley Brown from Huddersfield) I was obviously not photogenic enough to make the pages!!. Folklore is great but I cannot recall seeing it on vinyl, and I was in the 'know' at the time.
Happy hunting to find one.
