As you noted, that's duckpin bowling, which uses differently shaped pins than "standard" ten pin bowling; shorter yet heavier. The New York Times did a nice mixed media piece a while ago on the sport and its fading popularity, which in part is because the additional difficulty in creating a mechanized pinsetter for this type of pin. There was a successful pinsetter invented, but the manufacturer went out of business in the 70s and declined the license the patent to other companies. Now there is a dwindling number of vintage pinsetting machines left, many of which have been cannibalized for parts to keep existing machines running.

We have this in Argentina, at least where I live is called Boliche. I think is the same game after reading the rules, main difference is that the ball is smaller and maybe heavier without holes for fingers and you have three per frame instead of two as in the other bowling . Pin setters are common

Interesting. This might in part explain why duckpin has been fading from mid-atlantic states where it use to be quite popular.

Out of curiosity, are they faster or slower than mechanized pinsetters?

They are faster but only if you aren't waiting on them to set someone else. Also due to the nature of duckpin, strikes and spares are harder to get so they typically aren't setting every pin.
