Chris is right about there being quite a few turreted 432,s.
Other than the development they were supplied as kits for the units to fit themselves.The procedure is covered in EMER,Tacked Vehicles E105/2,Installation No.8.
These soon proved to be very unpopular and unsuitable for the role intended and were soon removed from the vehicles and returned to wherever.
A number survived in the Berlin Brigade and I believe there were some at Warminster.
What remained of the vehicles/kits went through Withams a while back but I didn,t see any complete vehicle instalations.
Although using the Fox turret the turret basket was totally different,although looking quite basic it was quite a work of art.
I,ve managed to aquire just about everything to complete my vehicle,the only thing missing being the flat hatch which replaced the original commanders cupola which I,ll more than likely end up making,that is unless anyone out there has one.
Although up and running there is quite a bit still to do but we,ll get there one day.
Here hopefully is a pic or two of my vehicle.
