Hello Don,
I haven’t had time to take a detailed look but there are some barrels with damaged bluing, or they’ve had a couple of inches cut off from the breech end. I saw another that seems to have failed QC as it’s labelled ‘poor accuracy’. They are all threaded for a silencer at the muzzle I think.
It might be worth machining one of these for your project, rather than taking a perfect barrel that someone might want to fit to their Phoenix.
If this would work for you, please drop me a PM with the minimum barrel length you require. You only need to pay the post and packing. But do look out for a future update on the thread, about where to make an entirely voluntary charity contribution.
