14 x 2,

£325 plus post,
UPDATE - more info
Have pictures, this is a massive wand customised by Greenie (Guy that makes Greenglides)
It has 2" tube for running 2 inch all the way 14 inch head.
Feather touch valve - no clunk with high PSI
High shear jets - means you can use higher PSI because of the angle of jets, and less heat loss as the jets are closer to the carpet.
Check valves - stops drips from the jets when trigger is not pulled.
Good wand for doing large areas quickly.
Hydramaster was selling these £700 plus VAT.
