Managed to dig out Jane's Armor & Artillery 1981-82. Apparently only one was built as a commercial venture. Front armor could stop 25mm rounds @ 1000m, side armor 14.5mm rounds @ 500m and rear armor 14.5mm rounds @ 800m. My feeling is that this design would be fighting vehicles it had no business facing; if you miss or are outnumbered the thin armor won't save you. I can't see much of a market for it.
Just my 2 cents...
