Every grandfather clock in the renowned Gershom Parkington collection is now in working order and on display at Moyse’s Hall museum in Bury St Edmunds for the first time.

St Edmundsbury Borough Council is trustee of the collection – valued at £8-10million – which was bequeathed to the borough by Frederick Gershom Parkington in 1953 in memorial to his son, John, killed in World War Two.

Alex McWhirter, heritage officer, said: “Our ambition is to display all that is possible from the Gershom-Parkington bequest.

“Some of the collection is just parts and there are also timepieces that have not worked, possibly since they were first acquired.

“We are using these pieces and the generous bequest to bring as much as possible back to life.

“We have spent a little shy of £4,000 on the challenging task of restoring the remaining three GP long case clocks with the result that every long case clock is now working and on display for public enjoyment and research.”

The long case clocks have now joined all of the Augsburg clocks, bracket clocks, watches and dials on display.

Councillor Jo Rayner, cabinet member for leisure and heritage at St Edmundsbury Borough Council, said: “The borough has an extensive collection which is actively restored and conserved by the Museums Accredited Heritage Service for the benefit of the public.

“I’m very pleased that people have the opportunity to see and enjoy the treasures we have.”
