Hi again "Tom",
Thanks for the scans. Clearly the author is identifying copies here. In the case of the communist era VM medal on page 334 he identifies this as a copy made by "J. Panasiuk by order of Max Purgala". On the following page is " the most well known copy made for collectors in three classes". I see that he employs selective use of translations into German, Russian and English. In typical Stela fashion he uses an abbreviated method of identifying various characteristics, in this case denoted A, B, C, D, etc, that requires you refer to a legend. This appears to be a very helpful reference.
