I picked these up on Ebay the other day after seeing them posted up on Dakka Dakka and thought I 'd share here to get them some more exposure, especially since they were kind enough to swap my order to the new gun style they had just announced! :)
Anyway, overall the quality is pretty good - only one airbubble! The one downside (and it's nothing more than you get with almost everyone selling resin models) is where the resin pouring gates attach to the miniatures - sometimes it's a bit hard to remove and not damage the model. Anyway here are the completed models with a token old GW Ork for scale purposes - purchased one artillery gun and 2 of the AA mountings for use on some Apocalypse sized vehicles.
