Nice looking Mark King standard on eBay. Wonder what's hidden in the electronics cavities besides the electronics given that the seller indicates that the weight witohut the case is 30 lbs. and You may find having a guitar stool handy.

Wow   30lbs! it's those darn 20lb lead necks!

30 lbs.  Impressive.  By the pound, it's a good deal.

That must be the one with depleted uranium hardware.
