Thanks to everyone who answered, especially Tom- your advice was very helpful.

I have been rather bewildered by the number of different names that seem to exist for this instrument and its cousins and how they vary depending on where you look. It also seems that there are different names for them in the US and UK.

The scale length is about 41 so it sounds like the strings I have are of no use, I shall try a set at the gauge you recommend.
