The engine parts (reaction Chambers) were originally made from plastic pieces sourced through Engineering Model Associates or Plastruct these days. I found the prices way too high when I recieved the catalogue so I went to Home Depot and found some 2" OD ABS pipe and to a craft store and found one dozen plastic styrene eggs. The bottom of the hollow pieces were the perfect hemispherical size and the ABS pipe fit the plans exactly.

The Alpha decals here are ones I have obtained from Chris Trice and they are no less than perfect, I have come to regard this as the standard for Mr. Trice. The heat shields shown are 1/32 fine textured plastic. I have made the manouvering thrusters from these pieces. These nozels are from the Gemini Kit and they are mounted on a small block of wood to make a master then copies made for all the pods. I think they look nice once painted up as above. note the tiny air bubble in the casting. This was not evident untill handling the model colapsed it. I used urethane resin and I bet I did not probe the mold well enough to work all the bubbles out. I will have a vac-preassure pot made for the next set I make. That should disapate the bubbles.
