I guess we all agree that these 2 hilts are of the same style.
Still, I'd be very cautious of any claims like same maker/workshop/school - successful designs tend to get copied very quickly!
My best guess would be that this non-traditional hilt reflects the European influence during the first half of the 20th century (up to Indonesian independence) in Bali (or, possibly less likely, Lombok). I can't rule out a Madurese origin nor Kota Gede work though.
Regards,
Kai
