Hi Johnb, I'm based in Jakarta too.
west Jakarta , Have you ever look at the antique market in surabaya street?
I used to look for swords in that place...but you have to make a smart bargain there. I send you a PM . I really like the tanto you found for $100...like to see it since I never see a tanto before... it would be nice if you can help me with my sword.
regards,
