Rather different as it first appeared to be solid cast blocks of resin, but when drilling the holes for the rod to set the tracks on I discovered it is actually hollow. So are the outrigger tracks. The resin is extremly soft, and powdery when sanding. The white metal parts leave a lot to be desired, and I replaced a lot of it with scratch-built from plastic stock items. Added the rivets with Tichy Train Group rivets. The one tire was off so much, I basicly carved close to 1/3 away on one side to get it somewhat close to the other three.
I could only find three photos of this "Tank", for references, and have a few more items to change to match-change- or come closer to those I found on one of the Spanish Civil War sites. (Sorry, I'm old and don't take notes, and don't remember which one)
