This I see as an omission in the otherwise indispensable Morse:
Duels of sets of like figures (methinks Dobrila worked on this
theme and I even read an overview article, but I can't find
it anymore) are only shortly noted (#156-159).
Anyone have the data? (Obviously, the records may get
heavily boosted by using promoted material, so it's
probably wise to give both records, with and without.)
