This manual has PNs through the 1979 models. There is a revision E that has
some different part numbers for the 1980-1983 planes, though not many parts
changed (to 105-prefixed Duchess numbers). This manual won't show the
applicability for the pre-1978 12-volt models, though most of the part
numbers remained the same.

I just spent the $156 to buy the final-revision manual from Beech, after
giving up on finding one on eBay. Let me know ASAP if any of our mail list
participants wants my old one for $40, postage included to the Continental
USA via Media Mail. Otherwise I will stick it up on eBay for that as a
minimum bid.
