Thank you very much Ronnie42, Mitch and Barry for your encouragements. The build is progressing well. Its a unique build, something I have not seen before so its a fascinating experience for me to experiment ideas I have and see the results.
This post is for the turret basket with a YouTube Video of the turret rotation in action.
It is difficult to find pictures of the MRV interior. Most shots are from the same angle, seen from the rear ramp and always showing the back of the turret basket, which created some grey area that I needed to bridge with some assumptions.

This set of 1/35 graphs from the book Australian Fire Support Vehicles were highly useful, but not much detailed and with many grey areas.

The base for the turret inside the hull is created.

The turret basket was built in a telescopic fashion, one item at a time, through extrapolation of fragment of interior pictures and the simple graphs available.

A beam was added at the front based on assumptions. The basket needs to be solidly fixed under the turret. It does not show but the positioning of the basket is one of the most critical step of the build. In order for the turret basket to turn correctly, it needs to be perfectly centered at a precision using tenth of millimeter. It was achieve through trials and adjustments using small drop of superglue. Once the optimal position is found (meaning the best I could), then it was solidly glued in place.

Seats for commander and gunner. Ince the wire for turret rotation servo is shown. The others are temporality store inside the turret while I am building the basket. They will be positioned later.
