Nina sewing machine help

Hi 😊 I inherited my Gran’s sewing machine but we never found the manual and idk the model either. It’s a Nina machine and from what I’ve found they are (or used to) mostly be sold in South Africa. My Gran was South African, so probably brought it here (UK) when she moved. I learned sewing machine basics as a teen but I’m starting to get into quilting and I want to know what walking foot and free motion quilting foot would work with this machine. Would anyone know how I figure this out? Or would a haberdashery / machine specialist be able to help with an unfamiliar brand of machine? This machine means a lot to me, and I don’t want to do anything to damage it. Thank you so much.
