Source Serif  Sugerida por fmontpetit 

Source Serif not fit as original can you kindly suggest same font.

I'd have said Source Serif as well. If I got up earlier, that is

To be honest, there is a tiny difference with the capital "M"... But these open source fonts get too many revisions and today I don't feel like going thru all of them just to find it. Plus, my shift is pretty much over as yours begin...

OK, Thank you so much for your effort.
