SJ-200 question

Hey guys,

Dumb question. Saw an SJ200 Original Vintage Sunburst on sale. Online it has a strap button on the neck. When I got it home I realised mine doesn’t. It’s a legit store and there’s no issues returning it. I was wondering when did they start adding strap buttons to the neck of the SJ-200? Also is it worth getting it exchanged? Any advice would be appreciated.
