[[entity-ulrich-kaltenborn]] ("trzes"), a specialist collector who has built his own
reconstruction of the Topkapi Mamluk deck and engages directly with both L.A. Mayer's and
Michael Dummett & Kamal Abu-Deeb's academic texts on the deck's structure, offers his own
account of why the Chinese coin-suit symbol was reinterpreted as a polo-stick on reaching
the Islamic world. But he frames it explicitly as his own reading rather than a citation to
either academic source: "apparently," "probably," and — for the specific resemblance
reasoning — a parenthetical "(see Wikipedia)" rather than a reference to Mayer or Dummett.

This matters because spiorad.net is otherwise a genuine independent Tier 2 corroboration
of the Mamluk deck's structure (suit names, the polo association of the polo-stick suit).
But on the one point the vault most needs sourced — the *mechanism* by which the coin suit
became a polo-stick suit — the specialist source that most directly engages Mayer and
Dummett's texts does not draw on them for this claim. It points back to the same uncited
Wikipedia sentence the vault's own claim traces to.
