Looking for vintage Ska badge replacement

Hi, I'm looking for one badge in particular. There is a series of vintage badges that consist of 7 total that spell out Specials (S,P,E,C,I,A,LS) I am looking for the "I" badge. I have a vintage trench and somehow I lost it. If you can help me find it I would greatly appreciate it.

PS Going to see the Beat at the Canyon Club in Agoura Hills, CA next month!
