Help with older (1999) AC full face helmet

Have an older full face Arctic Cat helmet. Bought it in 1999. Under the foam it says "Model Arctic 301, Manufactured by Tesh manufacturing, Inc". Tesh appears to be out of business. I need a new breath deflector for the unit and would just as soon not buy a whole new helemt because of this. Anyone have any idea how I could correlate this to an Arctic Cat model no. and where I might go to find a replacement breath deflector?

Thanks!
