The C16R ran at least from 1995 to 1997. Maybe even into 98 according to Orange, and some owners believe they have a 94 C16R.
My 1995 frame is one of the lightest steel frames I've ever weighed, even though it's a size 19, and I'm pretty sure you wouldn't say that about a P7 of any year, so I still think the C16R was lighter than the P7 in most if not all years.
Size-wise, they come out quite small. An Orange size 19 feels no bigger than a Kona size 18, even though the top tube is higher.
