Returning to old discussions.

Today i see technical manual to MiG-21PFM (1969 year issue) - it is not different between this submoficaton (as say in this book from Gorkiy aviation plant), this one boook for both submodification, it is only one differences - two subchapters in chapters about canopy (one piece canopy for early PFM, two piece canopy for late PFM) and seats (SK - early PFM and KM-1(1M) for late PFM).

As write in this manual both PFM version had SPS system with absolutly eqail control panele this sysytem.

So SPS system vas mounted on both submodifacations MiG-21PFM.
