It is the one blackletter most people have met without going looking for it, because it sits in the font menu in Microsoft Word. Monotype's Type Drawing Office drew it, Microsoft licensed it, and it installs as a file called Oldengl.ttf. It is small, it is old, and it has been shipping for decades. There is one font style in the family and no separate bold or italic, so the Old English Text MT font family is a single cut and anything offering you weights of it is offering you something else.
Worth thirty seconds before you download anything: open Microsoft Word, or any app with a font list, and type old into the font box. If Old English Text MT appears, you have it, and everything a download would give you is already on the machine. Set your heading in it, print it, export the PDF. None of that requires this page.
What it will still not do is paste. Setting a word in it inside Word produces a document that carries the styling; copying that word into Instagram, Discord or a browser field produces plain letters, because the shapes live in the file and the file does not travel with the text. That is the gap the box above fills, and it is the only thing it is for.
