I was wondering who got that gun when it was for sale a few months ago?
That's a nice stick of wood you're putting on it.
I'm interested in these DT small bore 21's and am currently in the final phases of doing a custom upgrade on a DT 20ga myself. I just received the metal back from Angelo Bee who engraved the receiver & some light adornments on the barrels. Now it's onto bluing the barrels & final assembly.
Good luck with your project & keep us informed as things progress, I like what I see so far.
