Hong Kong company mainly known for making plastic boats and submarines in the 1970s. The submarines were one of my favourite toys as a kid. Repeatedly diving and resurfacing was so exciting to me. In the deeper , murkier pools , the submarine could sometimes disappear from view which only added to the excitement as it reappeared. The patrol and torpedo boats had a very good turn of speed with their submarine motors. Very nice looking boats and submarines.

Plastic battery operated battleship. I think this is modelled on the German WW2 heavy battleships , the Bismarck and Tirpitz. Comparatively rare for a Playart toy. 386 on bow. Turned on/off by rotating the main control tower. A lovely little piece.

The fantastic Playart submarines were definitely one of my favourite toys of my child hood. The submarine on the right is the earlier version powered by the same slide on motor that powers the Playart Torpedo boats amongst other Playart boats , and incidentally many other boats from other manufacturers of
this era.

These submarines dived and surfaced repeatedly . You could adjust the depth they dived to , and also make them cruise on the surface. The submarine on the left is the 'improved' version powered by two Penlite (HP7 , AA) batteries , as opposed to the single Penlite of the earlier version, held vertically under the torpedo behind the conning tower. I and a friend had endless fun with these when we were kids. Superb toys.

Because , as all submarines , whether real, model or toy , they are sensitive to buoyancy, modern batteries being a bit heavier and bulkier than the old 70s Penlite HP7 batteries, it's sometimes tricky to get these submarines to dive correctly.

Playart Torpedo boat with 'Hi-Rev' Gold seal motor. The 'submarine' motor could be detached from the hull . It was powered by one Pencell or HP7 which is the modern AA. The boat has a surprising turn of speed considering it was powered by only one cell.

This jolly Playart  'Sturdee' tug is one of the many Playart boats issued by the Hong Kong company in the sixties / seventies.
The single AA cell  is housed in the funnel. The tug is turned on by twisting the funnel.
Unlike many Playart boats and submarines, which used the external 'submarine'  motor , the motor is housed internally.
