Wooden toilet seat (Fulbourn CB21)

1990s wooden toilet seat. It's been in our shed for 25 years because we didn't like it much. May need an "M6" screw fitting -- can probably find something appropriate if you don't have one to transfer. Lightish (pine?) wood, hard varnished, with chrome-plated steel and diecast zinc hinges. Can fit most toilets provided there's access to do up the nuts under the hinges.
