That looks like a nice bike!
If i was you i would strip everything off of the frame and start again.
Without all of those crappy components (which most have been added later) cleaned and polished it would be a very nice base to build a bike.
To me it looks like a late 1950s early 1960s bike, the saddle might be as old as the late 1930s due to the shape.
If the bike is from that period i expect the brakes are Mafac Dural.
One strange thing though is that it has eyelets on the front for fenders and maybe a rack but no eyelets on the rear dropouts.
