I'll try & sort this out for you at lunchtime (I can use the scanner/copier here at work) But I don't think it will answer your queries regarding the bearings. The Meteor came as standard with only two ballraces - the pair in the gearbox that the diff runs on. Earlier Meteors had brass bushes in the rear hubs which could be replaced with ballraces - but later ones had hubs where the stub axle runs direct on the plastic of the hub!
Optional wheels were available with recesses to accept bearings (Early option three piece wheels seemed to take smaller bearings than the later one piece dish type which accept the same size bearing as Mardave Cobra wheels)
Extra bearings can be added into the gearbox - one inside the gearbox to carry the end of the intermediate gear shaft - the other end with a bearing inside the gear cover. There is also a ball raced version of the red spur gear that is recessed to accept a pair of small bearing - very hard to find this part!!
