There are always more to collect!
There were several other versions of the Dinky Toys' Sea King.
There is the Bundesmarine variant. It used to be rather common but as it dates to between 1973-78, few are found today complete and original.

Some of the early versions of the Sea King were battery powered.
There was also a bare metal kit issued allowing kids to make many other versions. It had the battery and motor supplied.
But, by far the rarest one, and IMO the nicest one, is the Army variant in Olive Drab
It was issued in 1979 as the Dinky Toys Liverpool production line was shutting down due to bankruptcy. It never entered full distribution which explains why it is rare, but as few people know about it today, it can be found at very reasonable prices from time to time, but normally without full packaging..
At the same time the Dinky Bell OH-13 helicopter was also in Army colors and is equally rare for the same reasons.
