This is an original post war 1952 Turtle Shell Helmet MK IV. This example is complete with 1952 dated liner. We are unsure how old the helmet is as we can’t seem to find the markings. It is most likely a war time example with a post war liner. This example is in original condition with 80% of its original black paint left. There are no serious dents or damage to the helmet. It has its original 37pat style chin strap which is also undamaged. The liner is complete. It’s has been left exactly how it was all those years ago. It could do with a light clean if you wished. Currently in un touched condition. This example as well as a few others were found in the original owners shed who had left them hanging up since the mid 1980s. The helmet liner is a size 7.
