Thread:User talk:Rua/Confused about "lintrum"

Hi! I don't understand why my edits to the entry lintrum were reverted. If I've understood the linked du Cange page correctly, it doesn't provide any support for this as a genitive plural form. It seems to be giving it as a nominative singular form of some word, which I think would have to be second-declension neuter; but if that's too much of an assumption, I guess the page should be deleted altogether (unless you know of an alternative source that supports its existence as a genitive plural form).
