I can see the top of a bell from a pushbike, upsidedown maybe but it's not the image I took this from :) The top one I am sorry to say I have no clue what that is, but points for originality :)

Hint added now. Happy guessing! 😁

Noone guessed this one, but not to worry Round #3 is up now with this week's SBD rolled over so come on over, have a guess and see what last week's image really was!
