A handwritten fabrication note sits on a steel workbench beside a bent brass rod dipstick tube laid over scribed layout lines. The page sketches a curved tube with angle dimensions and reads '237 mm = 335 ml of oil' and '1°, 1 1/2° max for vertical mount', with notes about the oil fill/check hole on a York compressor plugged by a standard 1/2 hex head bolt; date stamped 21/04/2008 10:28.
