WTB Martini 12/15 action

[villagelightsmith]

Just one ... more ... project, before the colors fade ...
Like the title says, I'm looking for a Martini 12/15 action. It's the heavy walled version of the little actions. Purpose: I'm hankering to build a 225 Winchester. I have the stocks, a decent barrel, the CF conversion stuff and dies. It doesn't have to be perfect; all my guns are working models. They are not something to "perzarve." They're not lookers to show off and make silly brags about. The warrantees ran out on these a long, long time ago, and now they've gotta earn their keep.
There are a lot of folks here who know more about Martinis than me, which is most of it. As with every project of this nature, I'll likely learn a few things I'll wish I'd known before I started. Gotta get moving on it; the sage rats are about to come out!
Thanks!
Jerry

Ho-Kay ... what can I screw this 225 pipe onto? Are the threads the same on anything else? Or ... is that the problem the previous owner had with the barrel? [ I'm not even going to ask. ]
I'm still looking for a Martini action to convert to CF ... possibly a Fireball or a HeBee.
