I haven't seen numbers below a Columbus Dove stamp before, but if it's not a manufacture date code, it could refer to the tubing dimensions: 1mm butt and .7mm unbutted section.

Is the 071 stamp on the tube or on the lug?

^that's a bit of clever thinking there, USAZorro^, I have never seen a lug with the Columbus dove stamping whereas I have seen it on tubes (and occasionally panto'ed on a seat stay cap). It would also be a pretty slack angled lug still, it's definitely a thought to consider: howzabout it George?
