What organ/keyboard is this? (70s Nigerian funk)

Hey y'all,



Anyone know what instrument is used in this song? You can hear it alone at the beginning (starting with the very first notes), and it continues as the other instruments come in.



Is it some kind of combo organ? I'm not super knowledgeable about organs, but would love some advice/theories about this.



Thanks in advance!
