As you suspect, I think the reproduction quality is affecting the serifs and weight. Otherwise, these shapes precisely match Hermann Zapf’s Melior, the basis for this particular font. There are a variety of digital versions of Melior, including foundry-specific releases like Bitstream’s Zapf Elliptical 711 and URW’s Latino. Of those, Zapf Elliptical 711 has the sharpest outstroke on the ampersand, so that seems the best bet.
