MkII NHSR Helmet
I bought myself a nice National Hospital Special Reserve MKII helmet. These markings are normally found on MKIV’s so it was nice to find on an earlier helmet. It is marked front and back, slightly off center. Under the NHSR on the front the letters BMH are found which may mean British Medical Hospital.
The MKI liner is by J Compton Sons and Webb and dated 1938 (or possibly 39)
