EIGHT brightly coloured carousel horses formerly used on a children's ride at Frontierland were stolen from a storage area near the site.
The junior horses worth around 500 each were stolen between Friday, May 7 and Wednesday, May 12.
Three were later recovered but the remaining five are still missing.
Steve Riley, manager of the Ranchhouse said: "The horses are made of fibreglass and each one is around 2ft high and 3ft long, brightly painted in red, green and blue with a white background.
"Fairground memorabilia is popular, and Blackpool and Southport fairs both have charity auctions where items are sold off to eager buyers.
"These horses are collectors items and there is a big market for them.
"At the time of the theft a man was seen carrying one of the horses down West End Road and it's highly likely that someone local committed the theft or knows the whereabouts of the horses.
"The horses could be used to set up another small ride or sold on as ornaments for people's houses.
"I would appeal for anyone with information to contact police as these things are unique. Even if someone painted them we would still recognise the pattern."
