Possibly just corrosion - the previous owner had a leak and just filled
with water.

Check that the reservoir cap holds pressure - 1.4 bar.  Check for other
leaks, e.g., around the heater control valve, and for damage to the
front of the radiator itself.  Then flush the system with clean water
and refill with the proper antifreeze mixture.  If you have a head
gasket problem, the exhaust gases will smell very different after you
add antifreeze - an acrid, bitter sort of smell.

Any good garage should have a pump for pressurising the cooling system
while it's cold.  It's very hard to spot some leaks when the system
is hot, because the escaping water evaporates.  If the system is cold
and you apply 1.4 bar, you can see the leaks dripping onto the floor.
