The quality and consistency of Robertson pipes is legendary, and this Robertson set lines up with other 1950s Robertsons as a fine example of instruments made when George Kilgour and James Martin manned the shop.
The set has been well used over its 70 or so years of life, but cleaned up well with a strip and refinish. The chanter stock ferrule has been replaced by a faux ivory substitute that is extremely convincing. The bass drone bushing has been lost, and has been replaced with one made of moose antler, visible in the caps photograph below. The wood parts were all crack free. The combing is well worn in spots.
The stock bores are tapered, a practice that was quite common in the Robertson shop at this time. The tapered stocks are designed to reduce air turbulence within the stocks.
The previous owner had the tuning slides corked very nicely, and with a touch of cork grease the tuning action is excellent. The stock joints are all hemped.
These pipes played in typical Robertson fashion with a robust, seamless sound and great steadiness.
