looking for a two-part low G

Whistle
1

Hello forum,

I’m looking for a low-G that breaks into two parts, in order
to fit into a concertina case along with my other instruments.
The longest part should not be larger than 26cm (I don’t know
how much this makes in inches ; this in slightly longer than a
generation F) ; 33cm (as a generation C) would still be acceptable
as this fits the diagonal of my case.

Has anybody ever seen such a beast ?

The whistle body of Dixon tunable G is 34cm.

I think you should try to find a 3-piece whistle.
