A Larry del Grego re-do was something most Parker guys did not want, and still don't. Walk right past them at gun shows because they stood out like a new gate, especially the incorrect case coloring. Del Grego repair work was, and still is, quite good.

A Doug Turnbull restoration is hard to discern from the original, and sometimes only because you know there just aren't that many 100% Parkers around. But I would own his work without second thought.
