I had originally based the mortars and crew on fender washers but after mounting the Chinese field guns and crew on a base I decided to break the mortars and crew off their washers and mount them on a 60mm resin base I had cast up. I fielded the mortars glued to a base in a Disposable Heroes game without the crew and decided that I wouldn't do that again.
Here are the mortars in all their painted glory. It only took me five years and eleven months to get them finished. I have four more washer mounted riflemen to use for the fourth crewman but they are still a work in progress.
