This is a The Real McCoy's MA-1. Regarding wear frequency, I wore it about 4-5 times during the winter season until the year before last, but I haven't worn it outside since last year and have been storing it as part of my collection. There are a few small frays, which are shown in the last image. Although it is a vintage item and shows signs of aging, there are no odors such as mold, storage smell, or tobacco smell.
