The timeline is in the TA history, Bicycle Quarterly Vol. 6, No. 1, p. 8.
The TA cranks were introduced in 1960 with the pear-shaped axle. In 1962, they were replaced with the square-taper cranks (standard design). The earlier model was not a success, so it is likely that they stayed in various catalogues (including TA's) for quite a while - until stocks were depleted.
