The document is in Spanish; a Google Translate translation to English follows (I studied Spanish for one year at school but I am unable to significantly improve on Google's attempt. If any readers are able to provide improvements please let me have them, In particular I am foxed by the work Galluza which Google translates to Galluzo).
I have contacted the Museum of Decorative Arts in Prague who have said "unfortunately, there are no any watches with a signature of Kover in the collections of the Museum of Decorative Arts in Prague." Perhaps I have misunderstood the reference.
I am going to research the artists Augustin Heckel, G. M. Moser and John Valentine Haidt and will post anything I find of significance.
The prodigious machines (pages 87-91)
MACHINERY. Full plate gilt brass, with Galluzo decorated with masks. The Galluzo is one foot, is pierced with designs and located on the wheel, and is subject to the plate by a screw blued. The mask is classic watches of this era. The two plates are separated by columns and beautifully turned very characteristic of English watchmaking, while the watches made in France or Switzerland, these columns are usually smooth. The English take many forms, such as type or tulip baluster form, or the manner of Egyptian column. With Galluzo, it is the same, are pierced and decoratedsymmetrically. Not until 1750, when the Rococo influence, change these symmetries and shapes. The existence of chewing is very common in this era, especially in the watchmaking and sobrevolante English influence is always one foot, or anchoring in English clocks and two anchors on the continent.
