Air Ministry Salters No. 20T Trade Spring Scales

In a lifetime collecting RAF memorabilia, this is the first set of RAF issue scales we have ever seen. These are clearly marked on the brass dial with a crown, A.M. and 4A/NIV C22B and B122754/40, thus dating the instrument to 1940 and highly likely it served through the Battle of Britain. The dial is also engraved Silvesters Patent, Made in England, to weigh 150 lbs. On the back of the instrument is painted C Flight, although sadly no squadron details. We do not know the exact use for these scales but possibly for weighing kit bags and personal items prior to an overseas posting to calculate the aircraft's loading weights. We spoke to a specialist Salter's scale collector and he too confirmed the rarity of this item and suspect we will wait a long time to find another. It is heavy, so please check delivery costs with us before ordering. Dial diameter 15.5" (39 cm)
