Compost lid flew off in a storm – getting a replacement?

This terrace composter has been running without issues on a terrace for at least a decade. Last week a gust of wind must somehow have flipped open the cover, blowing it right off.

I have asked my neighbours if they had found it in their gardens, so far only negative responses. If I have to get a replacement, can someone maybe identify the make or brand of compost container? I have no idea how it originally ended up on the terrace!
