No labels or markings to read except the numbers outside. pickrknows, 4 years agoThis old dog has seen many-a-fire, these helmets are still used in some departments, but mostly went out in the 50's.It is definitly leather,(the new plastic composit ones would actually melt in too much heat), the old leather ones just get that weathered look.This looks like a '30's-'40's vintage,probably Cairns.Nic
