you're probably right about it being a 'home-brew' although the 'body' is apparently machine fabbed out of sheet-metal (well done).
And yes; belt 'twists' from the vertical shaft motor to the horizontal shaft on the central drive pulley — by way of an angled, spring-loaded idler pulley.
A second lever-activated idler pulley engages the power to the rear wheel hoop.
