Does anybody know how to contact Greg Jein?
You probably would need to send a message to him through someone who is already in contact with him. I worked with Greg back in the mid 1980's, and even then he was innundated with calls from fanboys wanting to see the props and models in his collection. He even told me he would get creepy calls at 2 am from people wanting to see his screen used stunt B9 robot. He's a nice guy but contacting him cold may be dificult, however a lot may have changed in 25 years !
