I assume that the 16 is referring to a 16 foot stop, or contabass probably flute.

The 2 is a 2 foot long pipe, for a flute sound. If you listen to the patch you should be hearing a high pitch sound and a low bass sound. I'd assume with the 2 it's a set of flute stops, sometimes called flute celeste on some ograns, stopped diapason, or flute bordon.

It's possible it's a string stop but I don't think that's likely.

Playing any organ properly without a large room is impossible without a pedal and some big time sustain. The notes should go out and die in a taper, like a good horn player playing whole notes, like long carrots, not bricks, or as one of my teachers says bullets not bricks on 1/4 notes.
