[ive been told marlin has been bought out] - Now owned by  Remington, w/production moved to KY.
 
[quality is not what it used to be]. - Nope.
 
[about when did this happen - After Remington aquired Marlin, and the old Marlin/experienced hands were no longer working there.
 
[how do i tell the good ones from the others] - Buy an older, pre-safety, pre-rebounding hammer model. Marlins with a letter-prefixed SN are the best.
