Cleared out my Mothers stuff good few years ago and she had my Cousin's stuff left over from her house in the Rhymney Valley, South Wales. This cousin's father sang, per the metronome he was presented with by the Hanbury Road Choral society in Bargoed in 1928 , so I think the Pitch Pipe and Tuning fork could have been his, or his brother's who sang for the Apollo Glee Club in the same town.
