Very nice specimens Bob!
Your Aragonite isn't from Molina de Aragón (Guadalajara) but from Minglanilla area, Cuenca, Spain. This is a classic mistake because Molina de Aragón is the type locality and for some reason many Aragonites from Spain are attributed to this locality, locality that in fact don't supply very good Aragonites... ;-)
Can I change your caption to Minglanilla?

Dolomite, Hemimorphite, Mimetite
San Antonio Mine (San Antonio el Grande Mine), East Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico
148.0 x 80.0 x 40.0 mm
Striking specimen of opaque cream-colored rhombs of Dolomite to 2.1 cm nicely perched on limonitic matrix. The Calcite crystals partly engulf glassy Hemimorphite crystals to 1 cm in length. Translucent yellowish Mimetite in spherical crystal aggregates to 3 mm are perched on both Hemimorphite and Calcite crystals. Some Hemimorphite crystals are broken where they emerge from the enclosing Calcite crystals, but they are not distracting. Otherwise, there is no damage. |

Thanks Mike.
A few more from Mexico....
| Description: |
Silver
New Nevada Mine, Andres Del Rio District, Batopilas, Municipio de Batopilas, Chihuahua, Mexico
36 x 25 x 15 mm
This native Silver from Batopilas is a classic example of the herringbone-style this locality is famous for. It has sharply elongated spinel twins, connected together in an aesthetic framework. What sets this specimen apart from most is the accents of snow-white Calcite, some showing classic rhombs. |

Picked this specimen up out of an old collection. It is marked Untersulzbachtal, Pinzgau, Austria, but it doesn't look like any of the typical Knappenwand material. Any ideas of a more exact locality and/or info on the locality?

Indeed a very good photo. And a superb specimen, Bob. If undamaged, it must be in the 4 to 5-digit range.

I believe is from Knappenwand and the white crystals looks to me as Calcite. Maybe you can check it with ClH?

Sure Bob, is from: Moscona Mine, Solís, Corvera de Asturias, Villabona mining area, Asturias, Spain, and here you have good info about this mining area that we uploaded from FMF Spain.
You can see other examples of these Barytes in the Spanish FMF Gallery -> https://www.mineralogia.es/index.php?searchterms=barita+moscona&searchauthor=-&level=search
I already added the right details to your photo
