So from left to right it's is:
DSB medium, AF dentless Boba cold cast, Target Boba, Boba Maker V3
I have started on my ear cap antenna and also some finishing work on the helmet. I used a couple of tent stakes that are cut down to the size I want and installed in the inner ear cap piece with epoxy putty.
I also went through with spot putty to fill in any pits and air bubbles in the cast where I cut away the visor or sanded on the under helmet ridge.
