As with the Leicestershire Bagpipes, all these bagpipes are Julian Acre's innovations based on various iconographical evidences and, as such, they are entirely non-traditional & hypothetical - but bloody excellent modern (Scottish?) bagpipes all the same.

In this respect I am presently working on The English (or Luttrell) Hurdy-Gurdy based on the hitherto called impossible hurdy-gurdy found in the margins of The Luttrell Psalter.
