Yes I definitely think it’s storm damage how old is it?
Half a season old
Most likely storm damage. Is the bat particularly dry?
SS so dryer than UK made bats (disclaimer based on opinions)
And does the bat have any faint grey areas, with what looks like micro cracking?
Haven't seen any grey areas on the bat.
It does look like the result of storm damage, but I don't see the characteristic lightning bolt marks - I take it thus damage has appeared after some use?
Bat has been used for half a season.
it looks that way, did you not see any signs before it went?
It's not my bat. I'm just refurbing it and noticed the damage. The owner new nothing about it.
