There are three sizes in that lid and they also come with a blue or a red star in a few different sizes. The black star is the more common one but still it's an Australian lid [] (I've never dug one), how wide is your one ?
That's a great site there [] , make one realise just how many good lid's there are from Australia.
Gidday, did you come from Au ? (just had to ask with a user name like that [] )
