What kind of sword is this???

[VVV]

When I found it I hoped that it might be a variation of the Jenawi from South Borneo but I have not been able to confirm it. The scabbard resembles those found in Banjar, even if the blade is shorter than a regular Jenawi.
The tricky part are the pentagram star and the European letters S.B. I have been suggested a masonic or rosicrucian origin. However, the sword is a quite heavy fighter and does not resemble any of the ceremonial swords found on the Internet. And the handle seems to be made of albino carabao.
Any ideas on the origin and other suggestions?
