I could wrong about the height, I've not measured how high so thought it'll be 5-10mm, the ground is not absolutely flat so some places may be 15mm, some 5-10mm.

Please see the photos here. One of the blades look slightly bent & reel is rusted from not used but other bits & pieces look clean.
Probably need servicing on the reel and bedknife, may be $100-$150?
