Warlord French tanks query, and rules for tanks only skirmish

[Vanvlak]

I seem to have developed an itch for French WW1 and interwar tanks. Warlord Games have a nice range of the beasties, and I am sorely tempted to but 3 or 4.
Does anyone have any experience with these, which seem rather nice?

And are there any rules for VBCWish skirmishes using only armoured vehicles in small numbers (up to 5 per side)?

Thanks in advance.
