Some books such as "Sengoku Armor Collection Book" list what is considered a 'Ranmaru MORI's armor,' but the armor was discovered in Hikone City by the chairman of the Japanese Armor History Society, Tatsuo II (then Tatsuo NAKAMURA), who sold it to an antique dealer in Kawagoe City, Nagayoshi OKUHIRA, and upon official announcement of their names, the two men have flatly denied that the armor belonged to Ranmaru MORI, stating, 'the armor was discovered and kept by us and is nameless (not Ranmaru MORI's).'
『決定版図説・戦国甲冑集』などには「森蘭丸の具足」とされる物が記載されているが、この具足は日本甲冑史学研究会会長の井伊達夫（当時中村達夫）が彦根で発見して川越の古美術商・奥平長良に譲ったものであり、両人とも名前を公表した上で「自分たちが発見、預かった品で（森蘭丸のものではなく）無名の鎧」とはっきりと森蘭丸の鎧であることを否定している。
