I say chaps!!! Tally-ho!!
Was checking out my equipment, and realised my tape measure was a bit gung-ho in the accuracy department.
Now, don't misinterpret the above statement, what, but you know what I mean, Chaps!
Looked at the table, and realised the calbitrometer (on the table, just above and to the left of my tape measure) had an extra hole in the bevelled end. Must have worn away during constant calibration exercises!!
I can tell you I was nonplussed for a while, until that new Greek technician chap, Calamari Meringue from Mollycoddlicos, happened to be passing and showed me how worn the splines were!
Cutting to the short of it and all that, realised the old tape measure hasn't got the appropriate sticker anywhere in sight!!!
Trust the Squadron Leader to dig a chap out of a hole with no thought for himself or any cheese whatsoever!
Hurrah for the Squadron Leader !!!!!!!!!!!!!!!!!!!!!!!!!!!!
Simpleton out......what!
