What does the numbers 87 & 31 signify on some of your leather sports jackets?
I would need to know the styles. I do not recall a 31, but if you mean 13 then that was the year our company was started 1913. This year is 100th. Anniversary but we have used the 13 on styles for many years. If you post photos of the jackets or the style number of the jacket I will try to answer your question better. Gail
