I think the RSLF(Saudi) operate a close brother to the OH-58 called the 406 Combat Scout.
Other possible light helo/reconnaisaince helo
Agusta A109
AS 350 Squirrel
Westland Scout
Are you sure the OH-1 is called Ninja and not taken from the bike ?
The BO105 i think is now produced by Eurocopter and formerly MBB.
