When booting into GSOS, there is a key press combination that will show all of the revisions of the Tool sets on the text screen. I am not sure if they show just the disk based tool sets, or also of the ones built into both ROM 01 & 03.Maybe someone else can shed some light on that.
You hold down ESC while booting. I believe this only shows the versions of the toolsets loaded from disk, though.
I've always found http://www.apple2online.com/web_documents/apple_ii_tech_note_26.pdf useful, but it doesn't note any variations in the ROM03.
