There is no marked size but probably a '2' or '3' (stores reference 22c/974 or 975). The aertex cloth is in very good overall condition bar a small fray hole adjacent to the centre rear buckled strap and light soiling. Both rubber earpieces look excellent and are very flexible. The interior of the helmet is really quite clean although both chamois donuts are a bit dry. Good chinstrap. All the goggle straps are good and three of the four press stud poppers have virtually all of their original brown coating. Wired with a pink flecked dark chocolate coloured instrument cord (loom, connector type 2091, reference 10H/4887), early brown cased type 119 jackplug and matched Air Ministry marked type 32 receivers. A good '+'/very good used example. Stock code H23479.
