Mike, I am pretty sure that it is the same basic mold for the turret as on the old Saladin kit. But I do suspect that Tamiya cleaned it up a little bit. I only built that kit once way back in the mid 70's and have no recollections about it at all. That is one that I wish that they would re issue.
Phil, most of the mods are all your doing! Except for the engine grill mesh, the thread "cable/wire" on the spool on the back of the turret, and that ammo can- that .30 has gotta eat. You mentioned them on another thread, so I had to go back and do all of them except the trim vane. But that got me looking at those in photos and on the various M113 models out there. Tamiya's trim vane appears to be an earliest type, while Academy and Italeri both have the extended lip seen on the FSVs.
When I was starting this build in 2008 (I plead the 5th on the rest of that story), I asked on here about the color used on Aussie AFVs. At that time I was told that originally the stuff was in US OD, FS# 34087, and later in the war the lighter shade was used. But under all that weathering you really can not pick out the the original shade of OD anymore
And YES, I do need the M113 LRV (is that the turret with the twin .30's?) and a Centurion Mk.5 for display alongside.
For anyone else planning on building this kit, these links have some great photos of FSVs in Vietnam
