WW2 British MkII Helmet - Blue AFS Decal

I good addition to any collection, a MkII No.2C grey helmet by manufacturer Joseph Sankey & Sons - the helmet lugs have been fitted over the last two digits of the date stamp. The helmet is fitted with a MkII liner stamped TTC (Teddy Toy Co) 1940 - size 71/4. Inside 100% of its grey paint remains, whilst the majority of the paint remains to the outside but has obvious signs of use. The original 'blue' London AFS decal remains. Painted above is a black square with 37 and a white triangle. (note sure what 37 signifies) As with the majority of helmets the liner is slightly crispy.
