Written on the brim, under years of dirt and dust it says. This is interesting because The Sand Pebbles movie was released in 1966. It was a movie starring Steve McQueen as an officer in the US Navy in 1928. I once took the helmet to a Hollywood movie prop store to inquire about it.
The manager there said that movie and TV studios usually do mark wardrobe items in this fashion. Let me be just be clear...However, I do know for certain that Steve McQueen did spend the last years of his life living on a property right here in Santa Paula, CA...
