Cracked

A non-bowling friend asked whether I could use a secondhand set of lawn bowls, maybe with beginners. A kind thought. He said he’d drop them round. Here they are. Issues are:
Large crack in one of the bowls;
Not a matching set, there are three different sets represented here.
The yellow Jack could be useful but I’ll check it’s size, it looks slightly small.
All is not lost. I shall offer them to a friend who turns such things into clocks etc.
I suspect there are millions of sets of secondhand bowls in peoples lofts.
