I've had this PI for ages, no idea of its manufacturer, I think the crewman is by Preiser. Most of my vehicles have some decal markings but I've never really paid that much attention to their accuracy. Since seeing some much clever and correct stuff on the Blogs' of others I have decided to put more effort into correct vehicle markings.
The 38t was not a great kit to assemble. Wish I had more of these but for a lot of my older stuff I just purchased whatever was available, and didn't really have battalion sized units in mind either. Again, don't know its maker.
