Help identifying an early 80's Ritchey

[JoniSteiner]

Anyone know which model and year this chap is?
I spotted it recently in a bike shop (where no-one in said bike shop knew what it was). I was just passing so didn't get the chance to look at frame number etc - although I guess I could go back.
Thinking to make them an offer if they are prepared to sell...

Another one for any Ritchey experts out there ... I'm thinking to buy this but not sure if it's worth £950 (?!). Also not sure about the frame size - the frame number is: 0 C 3 4. Advertised as 1983-4 Team Comp. I cant tell from the pics if this is a big farme or not - I am after small-medium (17-18 inch). Any help gladly received!
