Seems this SG-1F neck was made on a Friday after a long liquid lunch and the headstock is a bit out of whack.
Our good friend Dingobass has kindly drawn a line where the headstock should be shaped, so you can use that line or trust your own judgement.
Otherwise the rest of the kit is fine.
All yours for just $150.
