170mm WWII German artillery from Arsenal-M. I special ordered four of them from Randy at Fidelis Models. Randy is one of my best friends.
There are also etched brass bits too in the upper left hand corner.
Some of them are molded in gray and some in yellow resin. The resin is semi-hard and semi-brittle. I did not break a single piece while trimming them up. Quite a feat really.
