The group founded by Leonard Slye (aka Roy Rogers), and by co-founder Bob Nolan.
RCA Victor used colored vinyl to denote music categories of thier early 45 releases, green was used for country records. The cat# 48-0004 mean this was the 4th country release on a 45. Side B has a number 6 taped to it. I do not know what if is for. I'm leaving it alone but it should come off if you want. comes with original paper sleeve.
