Summary

10mm scale dwarf flamethrower unit for Warmaster based on the classic Warhammer 3rd edition unit. Two different strips.

For stats I would probably use the Leadbelcher/Blunderbuss statline:
Infantry, 3/2 Attacks (15cm), 4 Hits, 6+ Armour, 3 Unit size, 90 Points per unit, -/2 (replaces rangers in the army list)
I am not sure about the -1 penalty for armour though.
