Firstly, the 5½" discs:

Now the few Vocalion-produced Olivers which are 5½" diameter. Thanks to John Culley for these details from some records found in Germany.

Then there was a 5½" series with just letter identifiers, of which I just have the one example (sent to me by Richard Prout - see images above as well). Not to be confused with the 6" "alphabetic" series, listed later on this page. The same issues can also be found with the "Nursery Rhymes" label (q.v.), but it is not known how many of those issues can also be found as Olivers.
Here, I will only list the Oliver issues which have been seen, rather than make assumptions.

The 1000 series are 5½" discs, but are pasted over existing Mimosa records. This information, however, is based on the sole example I've seen (listed below).

Now, the 6" discs: There are two series, the 3000 popular and a Nursery series with an alphabetic catalogue reference.
First, the 3000 series.

Now, The 6" Nursery series

There were two 7" series. First the 0.1 catalogue; the nursery rhymes on the first 12 issues are believed to all be American recordings.

Now the 100-series catalogue (7" records). All known ones are American recordings.
