Hi Major Rob
You need to make some little alterations to the tamiya Leo ,like the smoke pots (they are included in the Italeri kit nr? ) the wheel chock blocks are moved to a different location,
you need to make a Motorola radio box on top of the turret, and some new antenna mounts,(U.S.style from verlinden) A very good article is included in Military Modelling of march 2003,vol.33 No.02 28th Feb-20th Mar 2003 by Bernd Zaeske.
If you are interested and can't get hold of the article , I can scan it for you.
If so please let me know at :
