I checked my "library" and you're right. Motor's repair manuals have a pretty good section on Carbs but they only go back 6 years. You'll need a couple of books for each decade to id them all. I have three motor's books that cover 1962 to 1979. I thought I had a couple of older ones somewhere but I don't know where I put them. I bought a couple of reprints of old Chilton's that I use for older cars. 40 to 53 and 54 to 63.They don't seem to be as complete as Motor's but they cover the most popular cars.
