I've just written a line of dialogue for a strip:
"DON'T WORRY, THESE ARE MK IIs."
Is that right? A small "s"?
Should it be "DON'T WORRY, THESE ARE Mark IIs" (ie no MK)
Or "DON'T WORRY, THESE ARE Mark 2s" (ie no MK, no II)
Which reads best? Is there any convention for this sort of thing? 'cos if there is then I don't know it.
