jokes apart... well... i've noticed a little bit of imperfections (a screw missing and a little piece of metal to glue in the revolving back...) tomorrow i'll do the repairs...
If you are talking about a threaded hole on the 4 inch side of the spring back (the back side of the back), my SCII has the same hole... and that is how it came from the factory. I have no idea what that hole is for but there never was anything in it.
