WW2 RAF Navigation Instruments By BWC

A very good and complete set of RAF navigation instruments by BWC (British Watch Case Co.). The set comes in its original webbing case, which bears an issue number and crown mark, and each large instrument is maker-marked as well as being struck with a tiny broad arrow, including the parallel rule. A previous owner's name is also faintly evident on the front of the case. Overall, the set shows little sign of use and is in untouched condition with patina and a little staining.
