Has anyone ever known of any Laskey mouthpieces (besides the 30H and 30G) being available in a Euro shank? Like 30C or 30F?

I have a 30He and I put it in my f today and really liked the feel and response, and it actually went in farther in the lead pipe than it does on my CC. Any thoughts?

Where did the guy that owns the mouthpiece get it from? What I saw on the Laskey website, the 30F and 30C are not available in a different shank. I don't know if I'd want an F or C, but I want to try them at least.
