Mantripp, a wood carver and sculptor from the town, said he had restored the pine structure three times.
It was first done after the Great Storm of 1987, when it blew down.
“I spent many months restoring it and re-carved more than 45% of it, it had new feet, and the back of its head,” he said.
He restored it again in 2002 following vandalism and it was renovated once more in 2017 after a campaign by the Bucks Free Press and The High Wycombe Society.
He said last year he noticed the tail had fallen off due to rotting.
“I feel some slight obligation to look after it. I’m willing to repair it and have quoted to do it. I want it restored and looked after, it needs to be done.
“If it was regularly painted it wouldn’t need restoring, it needs to be regularly maintained.”
