That bend just before the false edge is exactly like a pedang larus, and as you say, the guard also would be correct for a pedang larus. Very strange
How well does the point line up when thrusting? With a typical pedang larus, it is like pointing a finger with the right palm held vertically facing the right. Could it be designed for the tricky backhand thrust? (Right palm vertical facing the left, body turned sideways)
