Technical Uno Turbo Engine Mk1 or 2?

[prrace]

Hi All. Just new here. Great Forum. I have just bought a Uno Turbo engine to put in my 1985 X1/9. How do I tell if it is a Mk1 or Mk2? Previous owner had no info. It has 6D17 and M603AT.13 5997539 x2 on the block
Thanks
Peter

After googling M603AT.13 it seems to be the 1.3 lump...

Yep, definetly the MK1 lump you have. MK2 is M603BT13
