Mine is a 68 which is the second largest, it's also a Quest which makes it heavier than most. I read the larger helmets get a premium because our heads today are so much larger on average than they were in the 1940's so reenactors are driving the larger helmets prices up. That fireman's helmet I got for a couple of bucks is tiny in comparison to any other helmet I have, so much so I assumed it was a child's toy which the seller probably did also or he wouldn't have sold it that cheap.
