Can't find a match (it might be custom), but Egiziano Black is somewhat similar.

The answer is Apex Serif Bold (vllg.com).

Thanks Armin!

Yeah, sadly it's from the old days of Apex when the bold counters were way too small.

If you like those wee little counters, you will be happy to learn that Apex Serif is still in version 1, as seen on the Speak Up site. In fact, it's Bold (OpenType) Small Caps, which are outside the gamut of the mudTyper. (The next generation of the site's testing tool will accomodate OpenType.)
