If you can't tell which 400 version, post a pic. I'm guessing a 400A given the G model, but maybe a B. Either way, it ain't likely a straight 400 (like mine) and is, according to ample research, worth revitalizing in a lot of cases. We have few and poor choices for aftermarket for our airplanes, and a 400A or B will be a very steady position-based AP. You can still get them repaired too--virtually impossible with the straight 400.
