The stays indicate a TST made frame as I mentioned above, not necessarily a Kona frame. They made similar frames for many manufacturers, the first letter or letters of the serial number indicate which manufacturer the frame was made for. Some people do not like to give out the whole serial, all you need is the first part which they are happy to give as that is generic and not the run number at the end.
The decals look fine to me, though you never know these days and for that money it is silly not to check or ask for the serial to confirm the actual brand.
