It is often hard to tell certain types of bagpipes apart so we have put some pics up to try to help distinguish two very similar makers McDougall of Aberfeldy and Glens (made in Edinburgh).
McDougalls circa 1890s
The pics here show one way to distinguish between the two makers.
As seen below the measurement from cord to top of the bass drone is 2 1/4 " on the McDougals
on the Glens the same part measures 2". (As with a guide lines there will be exceptions)
On the projecting mounts on the McDougalls there is a round bead,where on the Glens it has been cut to give a flat edge (this is very comon on Glens)
This top has a small lip on the bush
Glens 1890s
McDougalls are considered the "Rolls Royce" of highland bagpipes thus sometimes Glens are looked at as inferior. This however would be a mistake. Each set should be taken on its own merits. Many top pipers including Gordon Duncan have played Glens.
The tops of this Glen are flat (with no lip on the bush)
Both Glen and McDougall have made sets with a lining on the inside of the tenor and bass tuning chambers.
Although I have seen several Glens with the lining in Brass , the one set of McDougalls that I've seen lined was in silver. A set of Engraved silver McDougalls would not be confused with any other set as the quality of the work is exceptional, I'll try to get a picture of a set listed!!!
I've got two other sets of glens and I'll get pics of them up asap, both are in Cocus wood and one is brass lined
