Codex 892 (Add MS 33277)

This manuscript is of the 9th CE and has one of the best texts in the Gospels. A first order witness.
Harris collated it: JBL 9 (1890) 31-59
He writes: "I do not ever remember to have examined or collated so important
a Ms as this."

An interesting feature is the use of "umlauts" as insertion signs.
Umlauts are a controversial feature of the famous Codex Vaticanus (compare here).
