I cannot stop coming into this thread and drooling over your sterling..
It is because of you I bought, well after the holidays, am paying for a new sterling body to have milled similarly. I have always wanted that though, so I'm not copying that much, but I am definitely copying the phantom barrel idea. Though, sort of always thought about that as well, just never pursued it since I didn't think or know it was possible.
Now I am reexamining the pump handle and bolt...
