I have <img src="smile.gif" width=15 height=15 align=middle border=0>. I didn't reply before because I didn't have the answer. IIRC both the G10 Centofantes (small and large) originally came with shiny clips. No serial # certainly means that it's not an early model as I would assume the first 1000 would have been numbered. Not sure about the clip position though, the only Centofante (large) I've seen had the clip below the pivot.
Life's too short to waste on instant coffee.
