Frank,
FR: You have the newer model I guess, if there is a nut retaining the die. I have a bunch of size dies that will work quite well in my Stars and they are stamped Saeco.
FO: Yes, I think mine is the "new" model. I know the really old SAECO's have the die retained by a screw on top of the die, not the nut below.
By the way, the site you sent in the previous post didn't work "address unknown" error message.
I know there is a fellow who does this sort of work out there. I did business with him or someone like him years ago when I had need. Ceck your address, I'd like to see if he'll do the job.
Good morning,
Forrest
