Yup al-onestare's right about the wrong rear mech, brakes and lack of P2 fork. Also not original for a '95 CC are the stem (it's Kona but from a later bike), seat post, saddle, cassette, wheels (rims and hubs), pedals and cable routing, rear dog collar is missing (removed to fit v-brakes). Also it's supposed to have SRT600 Gripshift, not the SRT400. Interestingly the '95 catalogue states 7 speed as per the bike pictured here, but late '95 model CCs were 8 speed in readiness for the '96 model year so this might be an earlier/mid '95 and/or it has gained the LX rear mech and SRT400 from a LavaDome or similar. So it's a bit of a mix'n'match bike bit looks quite nice anyway.
17" definately too small for 6'1", 18" also too small really and even 19" is a bit boarderline, though you'd be OK with a 19". I'm 5'11" and was fitted at an original Kona Dealer in '96 with a 19" frame, it's great but i wouldn't want it any smaller - just my experience but others may have other opinion.
