Here's the crew of the cannon, mostly White Knight/The Assault Group with a couple of Citadel models. Thanks to Matthew Street who donated most of the figures. I am glad I got these done before he got started on his puff and slash dwarves for the OWAC... they will definitely not be able to compare! :D
The mortars' carriages are from RAFM Crecy guns with the stocks cut, shortened and angled to elevate the barrels. I experimented with using the same wheels as on the large cannon but as the mortars are much smaller this looked a bit odd. I think they're similar enough to work with just keeping the colours consistent. The barrels themselves are the scroll cannisters from Warmachine Menoth preachers with one end chopped off and hollowed out. Again a mix of WK/TAG and Citadel crew thanks to Matthew Street.
The chief bombardier inspects the holy hand grenade, especially blessed ammunition!
