Mr Pascoe died suddenly, aged 60, in 2012, after being diagnosed with the chronic lung condition sarcoidosis. 

His legacy will be preserved with the opening of a new museum pavilion from 11am on Saturday, named in his honour, which will house more than 30 inventions that changed the face of agriculture in the region.

Entrepreneur Dick Smith AC is flying in via helicopter with his wife to unveil a plaque during the opening ceremony. 

“I’m pro farmer and always look to promote living on the land,” he said.

“And I love small country towns. I, like so many others, live in a city on the coast and it’s great to visit the outback, which is often viewed as anywhere before the the Great Dividing Range.”

Following the ceremony, the museum will be open for free for the rest of the day. 

Millthorpe and District Historical Society secretary Jacki Irvine said it had taken three years to complete the pavilion, with funding from the state government, Blayney Shire Council and Cadia Valley Operations. 

“Trevor was instrumental in the [the museum’s] institution,” Mrs Irvine said.

The day will also include the launch of the book The Pascoes, A Family Saga, a publication on Trevor’s family’s history. 

Trevor’s sister-in-law Judy Pascoe said he had been working on his family history for at least 40 years before his health deteriorated, including making two trips to Cornwall in the United Kingdom for research.  

She helped with finalising the publishing so the book could be launched on the same day as the pavilion opening. 

“He virtually had the book finished,” she said.

“It just needed to be typeset and that’s what we have achieved.

The event will include a barbecue, with Devonshire teas and coffee available. 

Entertainment will be supplied by Jason and Chloe Roweth.
