She was not scuttled at Tjilatjap so far as I know--although one sees such assertions--and even tho' I did find her listed as a victim of ARASHI and NOWAKI on 1 March, along with TORADJA at combinedfleet.com [which I must assume is Vince's source] here's an interesting, complicating fact: Binford had received word of such sinkings--a patrol vessel and/or a M/V being sunk in the vicinity of Bali Strait--prior to slipping through the IJN dragnet there; that is late on the 28th...
Unless ARASHI and NOWAKI picked up survivors of SH, I cannot see how her identity was determined, and I do not know which sources are used in the combinedfleet TROMs for those destroyers. I've not searched JACAR for any info, but if records still exist for DesDiv 4, then there would surely be something, I believe. It's not at all unusual to find such ship names recorded in English in the IJN records, for that matter.
SH was a very small, very slow, weak old auxiliary creature and burned coal evidently...
As I'm not at all concerned with non-Asiatic Fleet actions now, I admit I haven't ever attempted to sort out this (quite minor sinking) better.
