I dug out some old books including OSCAR: The Ham Radio Satellites by Dave Ingram, K4TWJ, and OSCAR Amateur Radio Satellites by Stratis Caramanolis, and the AMSAT Journal from December 1974. All three agree that in the Northern Hemisphere, AO-7 polarizations are as follows:
Mode B uplink and downlink RHCP
Mode A uplink LHCP
Mode A downlink linear
435.1 beacon LHCP
The turnstile is shared on both 2m and 70cm.
I hope this clears things up some.
