Tanker guys, I need help!

 JPZ-90
Unfortunately, when I was in the museum, it was just before to its closing time so I didn't manage to make notes about all AFVs I took pictures of. Sorry. Also I'm not able to identify this vehicle using my sources. That's why I'm asking for help.

I've got already some e-mails (from David Reay, Jay, Dimitris Labaditis and Bernhard Schiedek), and all of them wrote that it's German 90mm Kanonenjagdpanzer-4 (KJPZ-4), a 90mm gun tank destroyer built by Henschel and Hanomag.

But, according to Dimitris, it's probably one of 70 KJPZ-4s ordered for Belgian army and called JPZ-90. They differ from German versions - once again, according to Dimitris, JPZ-90 shares the same running gear with Marder-II. Is he right?
