Hehehe, then you're not old enough.... Not only seen them, I've flown them.... Back in the eighties, many helicopters still had collective pitch and AR bearing as separate options.
Cannot remember much of them, except for the MFA Sport 500 (actually a .45, but in size similar to most .30's) that I flew for at least 2 years intensively.
Fortunately never had an engine faillure....
