Didn’t the medieval scribes sometimes scrape off older texts already on the vellum...

No, they were a hidebound lot.

Okay, I have no idea if they did or didn't.

I seem to remember once reading that they are now looking for the original texts though some imaging techniques on older vellum’s that had been reused.

No, they were a hidebound lot. LOL!!
