One guy there on discogs claims the black one is the 1st press but it's just a speculation. Seems the matrix numbers are the same. Maybe just a random variation without any rhyme or reason. Or export version?
I have the red letter one, matrix A side: IW-1001A L-17904 Yes he still is (and something I cant decipher...)
I know Mr. Richards and dealt with him in the past, usually his answers to specific topics were cloudy if not unrelated to my questions But since none seems to know I might aswell try and contact him again.
