I like King Alfred's Grammar (https://people.umass.edu/sharris/in/gram/GrammarBook/KAGrammar.html https://people.umass.edu/sharris/in/gram/GrammarBook/KAGramm...). It's designed as an intro (and actually suggests Mitchell & Robinson as a followup) but it's well done. Not that much coverage of oral stuff, but unless you have a time machine you haven't told us about, that's not really the reason people study pre-modern languages.
