Bill Bishop, one of the last links to champion Queensland galloper Gunsynd, has died aged 91.

Bishop was the last of the four bush owners of Gunsynd who became known nationwide as the Goodiwindi Grey in the early 1970s.

Grazier Winks McMicking, hotel owner George Pippos, draper Jim Coorey and Bishop, a newsagent, pooled their money to buy a horse at the 1969 Brisbane yearling sale.

They bought Gunsynd for $1300 and the horse went on to win 29 races including the Cox Plate, Doncaster Handicap, Epsom Handicap, Toorak Handicap, George Adams Stakes and Queen Elizabeth Stakes.

He was the Horse of the Year for the 1971/72 season and inducted into the Australian Racing Hall of Fame in 2005.

Originally trained by Bill Wehlow, Gunsynd was transferred to TJ Smith as a four-year-old.

He retained a huge following in Queensland, nowhere more so than in his owners' home town of Goondiwindi on the southern Queensland border where there is a Gunsynd museum and statue.

"Gunsynd turned even little old ladies into punters," Bishop often said.

Gunsynd had a moderate career at stud and was euthanised at the age of 16 suffering from cancer.

Bishop's funeral will be in Goondiwindi next Thursday.
