Also no pictures, but "Fighter Squadrons of the RAF and their Aircraft" by
John Rawlings (rev. edition, 1976) mentions the fit as AI Mk.VI.

It gives example serials for Hurricane IIc :

HV709 L
HW341 O
HW435 N
KX359 Q
KX754 N

"So far as is known No. 176 Squadron used no squadron identity markings on
its aircraft."

Hope this was of some help,
