This part number can cause confusion as it has been used for two distinct tool kits
I think the kit Coxwellcourt is referring to is this one
This KBK100420 doesn't appear to be available new any more and to be honest all the reviews I have ever seen all said it was poor quality and over priced.
It is listed on a few suppliers sites, like the Moss Europe site
see here
However they all say that it is no longer available or enquire by phone.
Good luck in your search
