My advice with these things and the CRT monitors, having aging brittle plastics etc is that shipping is a killer for them, the Mac itself will suffer loosening of any extension boards and connectors, screw posts may shear.
The CRT will, at best, have it's tube coils shifted slightly that will unfocus or misalign the image. At worst the CRT will break.
You'll then have a refund/return problem. If the buyer is local, deliver it yourself - very slowly and carefully!
I have a garage full of vintage Apples & Macs I have owned that are simply not worth selling and shipping other than as " spares or repairs"
