Hello all just popping in to show you the progress I've made with the shunter.
This shows what I assume to be the forward access hatch, starboard side, I've drilled and cut out the molded grill and replaced it by gluing fine mesh behind it.
The main engine access hatches, starboard side, I removed the old mold by the same method as above and, as per above, glued fine mesh behind it, note the molded hand rail has been removed, somewhat crudely, with a craft knife.
Forward access hatch, port side, I'll leave it to you to figure out how I added the mesh.
Forward access hatch, port side, note again the butchered body work.
Finally an overall view, the 'OOTERS MISSING !!, removed with a craft knife, my finest work so far.
