"Bloke" is I suppose the most common Shelta word in daily use in this part of the world (and Australia).

Whatever the origin of the term, calling them "elbow pipes" (in whatever language) seems the most sensible way of describing the family of instruments which use a bellows operated by the elbow. The Irish version, or rather the Irish versions, are only some of the varieties in current existance. (Though I suspect quite a lot of these are revivals amd reconstructions rather than survivals.)

I came across a modern photo of some craftsmen working on a Hindu temple, and they were carving a big statue of the God Ganesha, who has an Elephant head. Intriguingly, he was portrayed in the statue as playing some kind of elbow pipes - which actually looked extremely like an Irish set. I know that the Scottish military bagpipe tradition was carried on in the armies of Pakistan and India after the British left - but it'd be interesting to know the situation regarding any other bagpipe traditions in the sub-continent.
