This helmet has appeared on eBay with the eye-watering Buy It Now price of £250. The seller has really laid on the history for this particular lid. It's not only a Dunkirk bring back but also has a Battle of Britain tie-in as well. I'm surprised it's not also Churchill's bodyguard Mr. Walter Thompson's personal bowler...
I'm also not overly convinced the CD and crown are period. The scratching around the letters makes me think this is a con trick used to age helmets. Imagine, if you will, you get a plain helmet at a car boot for £30. You spend two hours adding and aging a few letters and then plonk a price of 250 sheets on said helmet. My gut says caveat emptor here.
