As I have commented previously, many helmets identified as Cromwell were not Cromwell at all.? There were several U.S. manufacturers' that produced helmets that resembled Cromwells from a distance, but they were, in fact, superior to the Cromwell? John Lohrenz in Long Beach, CA made an excellent helmet called "Shoc-Shell, and Clymer made a good helmet, and there was a third whose name escapes me now.? Snell put all of them out of business.? I? still have my Shoc-Shell that I purchased in the 1950s.
