I remember this series very well also. I even went to the trouble of hunting down, just this past year, the short documentaries that were produced and found a set of all 39 in English. They were narrated by the VA for Mendoza. Unfortunately, they were all in RM format (second or third gen tape maybe) and the ends are clipped off abruptly. On only one of them do I even hear the end theme music begin after the doc. I'm guessing that they were produced for English language but never shown here, although they might have been seen in England or elsewhere. Judging from the music placement, it seems that they might have been placed between the preview and the end credits.
