From what you describe, what you have is almost certainly the Victrolac "Program Transcription" as Gary describes. How to tell: the album number is LM-127 as opposed to simply M or DM; and, the discs have a silver label as opposed to the standard red label for 78s. These are not "78s" at all, but early long-play discs that were cut at 33.3. The set is quite rare.
As for tracking, the grooves are narrower than those of regular 78s; my copy also mistracks with a standard 78 stylus. Mark Obert-Thorn recommends a 2.0 mil stylus.

I should have read your first sentence more carefully. What you describe as vinyl is actually Victrolac, a "thermoplastic resin" that Victor developed for the long-playing Program Transcriptions. There was quite a bit of discussion a few weeks back about Victrolac on this list.
Is the stylus picking up any dirt? Dennis Rooney described a problem with Victrolac records oozing sticky gook into the grooves. Perhaps he can respond and refresh our memories on this.

I never heard of Victrolac.
I'm sure the record is clean, because I just cleaned it.
I cleaned it with "PURE 2 - Professional record cleaner from by "Nitty
I has the scroll label and it feels like vinyl. Is it not vinyl?
