Jawa Demam region?

[erikscollectables]

Dear readers,

I would like your input on these 3 jawa demam hilts.
To me all 3 seem Sumatra pieces.
The one in the middle is relatively very big and hefty.

For the ones on the sides my idea was Minang Kebau and the middle one more to the north of Sumatra.

Well would love to hear your ideas on this.

Regards, Erik
