Would love to see one in plastic. We can always use more fire support. Still waiting on an M198 as well. It has been around almost 30 years without a plastic kit of it.
Trumpeter has made 2 1/35 kits of the M-198, #02319 late version and #02306 early version. I would have to pull out the kits to tell you what the actual differences are, but I seem to remember they are minimal and the parts in the kits are the same.
