progress M-54 with *M1* type external water(?) tanks

[ace5]

The progress M54 already being processed in baikonur seems to have spherical blue tanks around the refuelling compartment. This is a featura owned only by the newer M1-series.<br />Are they using mixed hardware (ie, some hardware from M1 to complement the "traditional" M design)?

just today I received the book "Soyuz, a universal spacecraft" great book lots of details, but already 2 years old<br /><br /><br />As I understood it the watertank in the M1 moved from the refuelling compartment to the cargo compartment, to make space for the extra fuel tanks. <br /><br />But on the M54 its supposed to be different you say. Have you got a pic or something because i'd be intrested in this. <br />
