We have discussed this here before at the forum so a search should find more discussion and the documents that spell it all out.
Of course George will know and be able to tell us as soon as he reads this thread.
Let s see who can find the official stuff (again) before George.
If you attended the Kelowna Convention you will have received the Service Information Manual I handed out free to all attendees, which specified the Official Cessna Service Letter that addressed this issue. (Hint: It came out in late '53/early '54.)
If you were unable to attend, you may buy this manual from headquarters.
George,
I wasn't able to attend Kelowna I thought I bought every manual from headquarters, but apperantly I missed this one! will you give the mannual number so I have it on record .

Thanks, Velvet,
I'l make sure I get the new manual, I have all of Dad's old manuals, that's why I couldn't belive I didn't have a 1954 setting of the props, That was regurlated and not Hear-say, thanks for your input!

Brad, ... while facing the aircraft, as if ready to "prop" it for starting,... with the #1 cyl on top-dead-center, the #1 blade of the prop should be at the 11 o'clock position, as if you are ready to grab the blade and start the engine. (From the cockpit this will look like hte #1 blade is at 2 o'clock.) Hope this clears it up.

Time to niggle. If when facing the aircraft as if ready to "prop" it for starting and the #1 blade is at 10 o'clock, wouldn't it look like 1 o'clock from the cockpit instead of 2 o'clock?
