Hi guys, thanks for the comments.
James, it's as Rudi explained it

Rudi, some of the parts are from the BaxMod set ( the rear turret bin, air filters, rear storage bins and a few smaller parts).
I started this build a few years back, the upper hull and turret are from Legend's 1973 IDF Cent conversion (the commmanders hatch is from the 1982 set), the lower hull (plus a few smaller parts) are from the Modelcraft Cent. During one of the many breaks from the build, AFV Club released their Cents, so for the running gear I adapted a suspension set from AFV Club, the smoke dischargers came from Cromwell Models. I'm also going to add a set of WWII Productions resin tracks. The headlights and other bits and pieces I've had to scratch.
Since beginning the build BaxMod released their own Olifant set, so that helped with some parts. Cromwell followed with their conversion, which builds into a later SANDF era Olifant ( I have one and will build that much later).
Cheers for now,
Dave.
