Selling z axis complete set up

[Pheet]

Decided to sell some of these Z'd heads to make some funds for my upcoming plasma build,

they are as per pictures and have a far over-engineered aluminium block, have servo motor as per picture, complete ballscrew assembly, rails and bearings, they have grease nipples too, couple of limit switches, and anything else ive forgotten, no obvious damage, peppering of corrosion, easily removed with a green scouring pad or wirewool
£50 each 36KG each so cant courier personal collection welcome, or you have your own courier collect, can strip down gently and post all part except ali block for £11.99 with parcelforce

Hi could you give a bit more detail on the z travel and bearings and width of the plate the spindle mounts to. I have a 4hp spindle to mount and it looks like it will do the job nicely.
