That is the Duprat "Maxi-" or "Maniplume" crank.
TA cranks are mentioned several times in Le Cycliste: Announced around 3/1959, but not yet available (and they didn't say it would be cottered!). January 1960: article on design, with cottered pear-shaped axles. 9/1960: Definitive Rebour article on the TA cranks.
11/1962: Square taper cranks announced.
I have seen the pear-shaped cranks on 1961 and 1960 bikes. Whether they were original equipment, I don't know. However, little else on the 1960 bike appears to have been changed...
