India. Bullets from India use a same or similar engine bracket, with big lug for the small center stand, not the larger one.
Additional input from Mark Mumford: India Bullet engine plates have the washers with internal hex; beware they may not have the the hex welded on with the same orientation as English bikes or, for that matter, the same as each other in a "pair". Another source of hex washers is the top of stanchions, if you have a stanchion damaged beyond repair. Recall the note in the shop manuals
about using the hex bar from the footrests as a wrench to remove the stanchions.
