Alexander Ross

Does this look familiar? 

In 1923 Mr. Alexander Ross of Kiltarlity Cottage, Beauly, Invernesshire made application for a Patent. 

The bagpipe pictured here was built by James Robertson for Ross according to the Patent specifications. 

The drones of this bagpipe are fitted with practice chanter reeds and the bores are such that a unique sound is produced. 
It is not known how many of these bagpipes were made by Robertson however probably not many.
Knowing that this bagpipe was built in the during the early 1920's helps us to determine a date for Robertson GHB's that are similar in appearance.

Note the use of black Catalin for the projecting mounts and the unique beads cut into the nickel ferrules.
