I have just changed R52 (on the Trader Sheet) from 100k to 10k and it looks like that is all that is required to obtain interlacing. If anyone is wondering why alternate lines are dim this simply the persistence of the phosphor and the camera shutter not being open long enough to average out the light from the two scans. In the first photo the rightmost image of the group of three is the TV22 with 10k. I've added a close-up of the 10k photo. Then another of the 100k.
