Just an update on this topic. Al Stiefel is retired. He is no longer making parts. Also, the socket that BMG sells are from Al Steifel. Their is someone else taking over Al's stuff for sale but not sure if he is or will be producing new sockets. I spoke with him at Tower Park in April and asked what his plans were. He is working with Al and the foundry to acquire rights to the molds. BMG is also trying to acquire exclusive rights to all sockets casted. Time will tell.
