As I mentioned Masuri have started legal proceedings with shrey so more information will be available soon.
You are on the right track, but on the wrong train.
Masuri did indeed send out legal letters to Shrey back in January (I think), but, having spoken to Raghav Kohli of Shrey today by phone, he has informed me that Masuri have since sent out retraction letters and will not be pursuing any course of action against Shrey.
So, in a nut shell, there are no outstanding issues between Masuri and Shrey at this point of time and nor is there any problems envisaged in the future.
Moreover, an increasing number of members of this forum have contacted Shrey requesting helmets, so the Shrey admiration club is quietly growing. Throw in the fact that everyday more and more international players are wearing Shrey's and it is easy to see that they are winning the hearts and minds of the people who matter the most - the international and first class players...and even with limited exposure and no marketing, the average amateur cricketer who will make up the customer base. People are voting with their feet.
As for the BSI tests, *no one* has passed them as they haven't even been held yet, so technically, no brand can be stocked if you go down that line of thinking.
Shrey will be fine and within two years will be the biggest helmet manufacturer in the world. Whether some nay sayers want it or not.
There are literally thousands of customers in the world - I am sure there is room for every manufacturer.
