An HO scale donkey engine and a set of logging pulleys. This test print arrived a little warped but seems to have straightened out OK. The whitish looking models have been soaked in acetone for 20 minutes to clean them, and they show the detail a bit better.
There are two pictures of the same block which show that the shackles actually move on some (not all).
You will notice the stack is broken on some pictures. I was trying to clean out the upper stack and ended up breaking the stack. These pictures are all of the same model, just before and after soaking.
