Actually, I'm going to go with adb club cricketer and say that it is indeed Shane Watson's. SS do make a few bats for Watson, I guess.
The aforementioned is completely possible as Steve Smith and Maxwell also use Indian bats. Maxwell gave one of his RNS bats (which was CRAZY HUGE) to the Director of Cricket at my club when he visited South Wiltshire CC.
Plus, when Shane is pronounced in the typical South-Asian accent, it makes sense why it was spelt like that "Shyn". Watson uses a 2.9-2.10. Plus, I've heard that SS Maximuses are usually liked by players. I mean... Rohit Sharma once used an SS Maximus where he removed the stickers and put Adidas Libro stickers on.
Completely possible. Wouldn't say that this was an off-the-shelf bat. Also, I think its pretty stupid to assume that the writing was done over the plastic, it was clearly done underneath.
Also, there is no toe-guard, etc.
Going back to what sehgal said, yes, sponsored players willow generally isn't available to the public, but when they come into shops due to a surplus or when they've been rejected, its more often than not, legit.
I've been told that the ping on this bat is crazy, so I'm probably going to go for it.
The onlinestockist could've done this with all their other bats as well, and pro bats are wrapped in plastic IF they're sent to a shop because they're there to be sold to customers in a neat and orderly fashion (well, that's how they do in India at least, not here much...)
