Herless (rebranded Ta Fu Yuan) TFY-618 Surface Grinder

I thought so initially, but now convinced the chain drive is definitely a conversion - the boss for the sprocket is welded onto the sprocket then machined off (leaving a small bit of weld unmachined), and the adjuster also looks like its been shop made rather than a factory made part.

So I'm guessing originally cable, converted to chain, then pneumatic, and now being converted back to chain :)
