The pictures aren't the best however there are some very interesting things going on here. Yes, there is the signature "Edinburgh" cut bead, but look at the gap within the mount. Very unique. Also look at the very subtle scribe lines on the drone ferrules.
I don't think the stocks are original to the drones. Look at the facing between the projecting mounts and the wood. Also look at the cord holders. I don't know if the chanter is original or not however it is pre-1900 in its profile.
