I discovered these vinyl buyers through their Youtube videos. They are looking for rare prog, folk and jazz collections. Videos on collectable Lp's and examples played on lovely Garrard 301 and Thorens TD124. For Marco's benefit - 12" arms and SPU.

Some expensive collectables including Led Zep I with blue cover. Some of the vinyl is a little too crackly by my standards though.
