I've always wanted to make on e (or more) of these as they are pretty cool looking little tanks. The one thing I've never found is a reasonable line drawing. If I had that, I would have given it a go, but I've never come across a reasonable drawing. Another thing that has held me back a bit is the lack of the suspension units, but I think I've figured that out. It appears to me that the X1A & X1A1 are no longer using Stuart suspension bogies, but rather, the units off an M4 High Speed Tractor. I've known they were not standard units since the first time I saw an X1A, but only recently I've begun to think that Bernadini swapped out the narrow Stuart suspension for the wider HST suspension in order to give a better ride for their heavier versions.
With the availability of the HobbyBoss M4 HST, this would now be a LOT easier to build.
Hmmm, haven't done a scratchbuild in a while. so if anyone can come up with any line drawings, I might just give this wee bugger a go.
