Good find! So this confirms that these were in fact meant to be produced/distributed here in the states, unlike how I originally thought mine was some sort of prototype or one-off deal. I was able to find another Dong Bang labeled unit on Ebay India as well, this one seems to be a rebrand of a Norelco SD-125 (which in turn is already a rebranded Dicon) but it’s a photoelectric model apparently. I bet mine is the predecessor to these. Dong Bang Electronic P106-91100 DC9V | eBay
