This shop in Greystance is selling a similar scope(GSO630: a newer version but same size) for $649 brand new on the same tripod. This one has a better finderscope, upgraded focuser and 3 eyepieces plus cooling fan.
From your photos I can only see 2 eyepieces. The other long "tube" inside the tray is a polar-axis finderscope that screws into the axis of the mount.
Hope you find these info useful.
Good luck with your selling
