That is a Solida alloy cotterless crank. Never knew they made one. See if you can measure the diameter of the circle formed by the holes in the chainring, or just measure the distance between adjacent holes. Those hole are for mounting a second chainring. If it is a common bolt circle size, you can probably buy an extra Campy, Stronglight or TA chainring to fit. If not, since the crank is cotterless, you might be able to use the BB with a Stronglight or TA crank. Might even be able to use it with a Campy crank, but this is less likely as the axle taper on most French cranks was different from Campy.
