I believe your Type I may actually be a Type II with the solid-line-under-Q flaw found at position 9. (If I'm right about that, you have the one position* of Type II where a primary Type-II spotting feature of a broken line doesn't apply.)
I believe your example identified as Type II has a closed C unlike any of the Type IIs.
Tony Clayton has done super work on this issue, available online here:
http://www.italianstamps.co.uk/king...e/index.htmlThe linked page shows more differences for distinguishing the Types, and then there are more pages for plating them.
*There were 25 subjects printed four up to make sheets of 100, so "position" 9 would appear 4 times out of 100. "Position" probably isn't exactly the correct terminology, in this case.
By the way, I'm no expert on these, and I'm happy to be corrected.
