Deep Purple’s label released just over 30 LPs in its 7 years of activity, the majority (unsurprisingly) either Deep Purple albums or solo albums by band members. It’s highly likely that Ritchie Blackmore’s ‘solo’ album would have been released on this, effectively his own label, but he insisted that his new project have nothing to do with Deep Purple and his management team created Oyster and distributed “Ritchie Blackmore’s Rainbow” through Polydor instead.
A few other minor LPs were released on Purple, and this is I believe the correct release order of all albums (sadly I’m missing just one LP, Maldoon’s second album, but this will be added as soon as a copy is acquired). If you’re wondering what happened to TPS 3511 and TPS 3512 (in between ‘Powerhouse’ and ‘Northwinds’ chronologically) those catalogue numbers were previously allocated to each of the 2 discs that made up the ‘Made In Japan’ set in 1972. Otherwise, here they all are, in order:
