I think you are right. Common silver mica types are CM-05, CM-06, and CM-07. As I
remember, the next letter is the voltage and then the three digits are the
capacitance in pFs. The first two are the value, the third the exponent of ten,
so 822 is 82 x 100 =8200 pF = 0.0082 uF.  The last letter is the tolerance, as I
remember.
