Yes, I think it was Oselli, but I am not sure if the radiator was special, perhaps only the lower mounting bracket, which in those days was very different to later Minis anyway.
The starting dog which replaced the crankshaft pulley nut most likely would have been the standard part used on Moggys, and probably other in-line A series applications, which as far as I can see from spares suppliers web sites, did not include the Spridget.
We tend not to need a handle for starting these days, as many Minis have an uprated alternator and some a larger than standard battery, but as it is so useful during engine maintenance, it would be useful if someone reintroduced the starting handle kit. A possible snag is that it used a bracket on the edge of the wheel arch to guide the handle, and so may be incompatible with 12" or 13" wheels, or arch extensions. But for those who prefer 10" wheels, and would like some original accessories, it may find a fair-sized market.
Edit: Does anyone have a photo of a Mini with the starting handle kit installed?
