Ngā Taonga Sound & Vision recently acquired an interview recorded in 1938/39 with All Black Trevor Berghan. The discs came from Trevor’s daughter Penelope Hansen and were recorded after the 1938 All Black tour of Australia.
Before the discs were deposited, I did some research and found that Ngā Taonga Sound & Vision already had some early recordings from that same tour in the collection – namely a short interview with the Australian and New Zealand Captains and the last 10-or-so minutes of the 2nd Test.
In this first audio excerpt All Black Captain Neville “Brushy” Mitchell and the Australian Captain Vay[ro] Wilson talk on the eve of the 2nd Test.

And here’s a snippet from the end of the 2nd Test on 6 August 1938 in Brisbane, with a brief mention of Trevor Berghan. The All Blacks won 20-14.

“Beautifully built with a fine fend and elusive side step he was a brilliant blindside runner and is ranked by former team-mates and opponents alike […] as the best first five eighths they have played with and against.”
The discs donated by Trevor’s family arrived at the archive last year in a rather mouldy condition (not surprising considering they were almost 80-years-old).
Because of their fragility, I had to then hand-transport them south to our preservation team in Christchurch.
Disc preservationist Sandy Ditchburn takes up the story:
Unfortunately, these discs were affected by mould and the lacquer was cracked and frail. They all required a stringent cleaning process. Ammonium hydroxide was carefully wiped across the grooves to remove mould, dust, and residue before the discs were washed and placed into an ultrasonic bath to remove any lingering dirt. An ultrasonic bath uses ultrasound (usually from 20–400 kHz). Cleaning occurs when the soundwaves agitate a liquid, which produces high forces on contaminants adhering to substrates.
A vacuum machine then dried the discs ready for preservation.
One disc in particular proved difficult to preserve/digitise. The disc’s lacquer was very cracked and small amounts had flaked off. Have a listen to this short example of my initial digitisation attempt:

Given that this disc was recorded at 78 R.P.M (Revolutions Per Minute). I concluded that it would be hazardous to try and preserve it at the same speed and risk the stylus needle catching in a crack and damaging the disc further. I set my turntable to 33 1/3 R.P.M. and carefully ran through the record at a slower speed. An especially bad area of the disc required me to lift the stylus needle off of the grooves and replace it repeatedly to try and capture as much audio as possible without a crack leading it astray.
Once I had captured as much audio as possible I used an audio editor (Audacity) to increase the audio to its correct speed of 78 R.P.M. and edit the broken parts of audio together. Using this method, I managed to recover the names of two mentioned rugby players that may have otherwise been missed.
After the preservation process was complete we could then make a “supply copy” which utilised “de-click” and “de-pop” audio filters, increasing the clarity of the content. Here then is an excerpt from the 1938/39 recording where Trevor talks about his early rugby life.

Ngā Taonga Sound & Vision also holds film footage of an earlier Bledisloe Cup clash, from 1936. Again the All Blacks comfortably win 11 – 6.
