Schutt Face Mask Code

[Claymore]

What year is a Schutt Face Mask with code DJH ?

or if anyone has a link to all the codes then that would be great !!

Thanks

Count the letters, with the first being month, then decade, then year. For example DIG would be D=4 , I = 9 and G = 7, therefore the mask is April 1997.
