One more upload for those who are interested -- this is the Level 1 Ceefax format the BBC used for 8 months between March 1996 (after the Level 2 pages -- which began in March 1994, were withdrawn) and November 1996 (when Ceefax received a complete revamp and changed to the current format used up until its demise in October 2012). As you can see, the pages and especially the animations here are similar to the pages used in the 'higher resolution' Level 2 transmissions - in fact a couple of the pictures are exactly the same so basically you could say that these pages are the same format but in lower definition graphics!
Footage very kindly passed onto me by Bryan Green who is the source of the material :-)
