Re Chugalug2's post above, something similar was witnessed with 103 Sqn in Cyprus operating the Sycamore 14. The CO was one of several 'Prices' who commanded helicopter sqns and this one was JL.
The Sycamore had a small cabin and hot and high, performance was poor. JL decided that to get the most out of the beast, arbitrary weights should be replaced by weighing what was actually tasked to be carried. He procured some bathroom scales and these were carried around and used where possible and they did make a difference but four squaddies instead of three was an advantage!.
Ever after, JL was known as 'Bathroom Scales' to identify him from 'Tailrotor' (that was JW) or HT, who didn't have a nickname!
