Here are some I made for a customer. Unlike the others I am about to post (that I made for myself), these are all permanently mounted armament, with a bit more attention to finer details. I snuck in a couple SD250s with mortars, cause they are permanently mounted weapons, but the 2 plain sand ones are for my own army.
Also, the 2 flame throwers are for my army. Those have electical wire for the fuel hoses, and included are the fuel tanks and pumps. Those have more detail than I normally do for my own pieces - mainly cause I plan to use them in every game I play.
