I have only one album on Folk Heritage Recordings, "The Fine Old Yorshire Gentleman" by Bill Price, plus a CD reissue of "The Jolly Machine" by Mike Raven and Joan Mills.

Discogs lists quite a lot of tha label's albums but tnis seems not to be complete. In their label profile they write:

UK label based in Wales. Specialised in folk and country music. Founded by Brian Horsfall and Alan Green. Linked to Mid Wales Sound Studios. Back catalogue now owned by Celtic Music [i.e. Dave Bulmer]
