Well, the last type (the G-21G) was FAA approved in 1969. I don't have reregistration dates, though; if one could get at the history of type certificate 4A24 that ought to have the best information on manufacturing dates.

G-21G has the most powerful engines…

It's a separate type certificate so legally it's a separate aircraft to qualify on. I understand there's some additional power lag (i.e. you can't get out of trouble with a quick blip on the throttle the way you can with a piston engine) but in terms of cockpit activities only the engine management will be very different. I would imagine a week or two of conversion course would be sufficient.
