[Closed] Difference between mk1 and mk2 Alpine?

I've ended up in the fairly daft position of owning both versions of the frame. I need to sell one, and was wondering what the differences are between them? From what I can tell, mk1 has a tubular seat stay bridge, whilst mk2 has a stencilled plate. mk1 has a gusset on the top tube, mk2 doesn't. Geometry looks slightly different, but I can't figure out exactly what - they are roughly the same size.

I suspect the decision will come down to the colour (one is red, tother is grey) but it would be nice to think it's an informed decision! Were the changes to mk2 to fix faults, or just improvements?

Cheers
