This Fire Guard Zuckerman helmet with "Boots" hand-painted emblem sold on eBay for £142 (+£6 P&P). I'm never too sure when I see these company-marked helmets like this. A number have appeared over the past year or so on eBay and most have been called out as outright fakes (for example, London Underground ARP Shelter badges attached to Zuckerman helmets). I'm currently on the fence about this one. The boot lace is obviously not original but the liner is.
UPDATE: I was contacted via email regarding the Boots logo. The blue ovoid/lozenge background was not used by the company until the 1960s. It was also originally a black background before becoming blue in the 1980s. Consequently, this helmet is a fake.
