For now, only @tigerluver is the rightful owner of the Padang mandible, and he is the only person who can eloquently interpret everything about this piece of fossil.

I did remember he had discovered that the Padang mandible was characterized by many broad snout features, and it is considerably broader than the specimen 2900-3.

And we are talking about a muzzle width that is potentially over 150 mm.

 If it's true,  the size comparison would like this.

 BTW, according to the 2016 research,  tiger and homotherium and marrian's dog were coexisted together in Pleistocene Java, here is the highlights 
Late Pleistocene tigers of Java belong to the largest known tigers
•
Tigers on Java had highest competition potential with Merriam's Dog.
•
Homotherium ultimum had the lowest competition potential with tigers.
•
New regressions for body mass and prey mass reconstruction for large carnivores were calculated.

Abstract
On Java during the Pleistocene, tigers of more than 300 kg occurred, but these are restricted to a single Late Pleistocene faunal unit, while Early and Middle Pleistocene tigers possessed body masses comparable to those of historic Javanese and extant Sumatran tigers. However, former studies have excluded carnivores from the Middle Pleistocene site of Sangiran where tigers co-occurred with machairodonts (Hemimachairodus zwierzyckii and Homotherium ultimum) and the large Merriam's Dog (Megacyon merriami). The aim of this study is to test if large tiger individuals occurred already in Early and/or Middle Pleistocene sites in Java and evaluate competition potential among carnivores from Sangiran and its consequences.

We calculated body masses and prey mass spectrum for tigers and potential competitors using linear regressions. Niche overlap was then estimated based on the prey mass spectrum after which niche-overlaps were used as indicators for competition potentials. Reconstructed body mass for H. ultimum, H. zwierzyckii, M. merriami are 154 kg (comparable to Homotherium from Untermassfeld), 130 kg and 52 kg, respectively. The niche overlap between tigers and Merriam's Dog is highest (100%) while it is comparatively low (60%) between tigers and H. ultimum. Tigers have not increased body mass before Ngandong faunal level, but competitors like Merriam's Dog seem to have decreased body mass to avoid competition with tigers. The sabertoothed cats on the other hand seem to have been unable to adapt to competition and went extinct.
