What filler did they use ? The stuff on the overarm on the tom senior looks like a plaster filler, something like polyfilla.
My S&B was covered in filler as well, but I prefer it with it removed so I won't be trying to replicate it.
I prefer unadulterated rough cast too. I always think it's half the character of a machine.It must have been very labour intensive, filling castings and then getting them sanded down etc, before paint.

Good job! I'm very envious of your heated work-space.![]()
