Signals for Teignford.

The Dapol upper quadrant GWR signals have been mentioned before.
Finding a discounted example at the recent Railex at Taunton made me decide to purchase one to see how it suited the position.
I am a little hesitant because of the mentioned failure of a number of these and don't want to drill a 14mm hole and bed in to find an early demise.
That's not to say that this will happen to this one- just an err on the side of caution.
