I'm collecting a few parts up for an Innova project and I was looking for an aluminium breech which I could only find in Asia. Louisvanhovell very kindly put me in touch with another enthusiast that imported them. I'm very pleased with how well made and nicely finished they are.
I also got the aluminium front pivot plug which allows a moderator to be fitted.
He also has an improved valve that has two outer orings for a better seal and a stronger stainless steel valve stem.
