5 string guitars

Hi all,

i am trying to find out if any genuine 5 string guitars have slipped through the net. So far I am aware of two instruments in the exhibition catalogue put together by Giovanni Accornero, one (altered to six strings) in Edinburgh, the 1774 Gagliano that was in the Heyer Collection and a possible Guadagnini in Brussels. And a couple of 5+4 harp guitars. Any more?

I know five course instruments were converted to 5 strings, but they are not what I am after.
