And here some more "brothers".
At first one mentioned by BluErf here, in post #3:

The sheath and pendokok are the same form, hilt a little more elaborate in carving, yet the similar style. There most probably is a trace of a sleeve covering the joint line between sampir and batang (similar sleeves are also found on Minang sheeths among others). BluErf attributed it to Sumatra back then.
Then there is a similar hilt form Dave Henkel posted here:

He wrote: "Another rare form. Sumatran most likely but God knows where. Still its very much a Bugis keris." Here I disagree, becouse Gonjo is not that of a common Bugis keris. It is completely straight and has signs of a small Tungkakan (as part of Greneng).
For comparison a Minangkabau Pangulu hilt. Here I should add, most probably Dan's hilt has lost much of its original surface with the time, also the Minangkabau hilt. They look well-worne, but one still sees traces of carvings on Dan's hilt.
