Others will chime in soon but I think that is a Falcon 'branded' Eddy Merckxx. They had a deal to use his name and made lots of different level bikes back in the day.
So it is a Merckx just not the level of bike his own company started putting out. Here in the US it would be like a Free Spirit at Sears with Ted Williams name on it. (he was a big baseball star or something)
