A rare steam-propelled toy tin-plate battleship is expected to fetch up to £60,000 at auction in Berkshire later.
HMS Terrible is part of a lifetime collection of toys and trains which belonged to Ron McCrindell.
Auctioneer Hugo Marsh said: "If it sells for that money it's going to be the most expensive single toy probably ever sold in the UK."
The 62cm vessel will be among 340 lots of toys owned by Mr McCrindell, who died in August 2011 aged 91.
In 1972, the collector starred in the BBC Two programme Ron McCrindell's Toys, in which he sailed the battleship on Hampstead Ponds in north London.
HMS Terrible was made by German toy-maker Marklin in 1905, famous for making transportation models and train sets.
The items are going on sale at Special Auction Services in Newbury later.
