Just the technical, quality item to check a Tractor Cylinder Head/Block for Warpage.
Became more obtainable via the Internet: it is now in my possession and not a myth!
Use with "Feeler Guages!"
If one has not got one one can't use one!
Situation perfect!
Thank you from,

Showed me a 0.08mm centre of block distortion and proved it was flat to at least 0.02mm (the thinnest feeler gauge I could find) after machining. Compared to competitors products, excellent quality and value for money; highly recommended for professional garage workshop use.
Used on measuring warping on aluminium heads, and blocks. Very good its protective rubber sheath is great as well for protecting the straight edge when not in use.
