This is about as close as you can get to the Twilight Zone or Outer Limits in aviation. While I think your 1960 C170 came with a AFM it was before the year it was mandatory so not all placards may be listed in it. To add to the references above, here's another list of possible references:
Yes there is, but very few people ever see it.. production certificate
You must know what you are building before you can design a system to build it. yer right placard requirements can change, as the aircraft changes, but seldom do except at a model / year change, then the placard requirement will change in the production certificate for that year.
For me, is the placards required by a field approval 337 or its ICAs. Especially back in the pre-STC Garmin 150 days when a "GPS for VFR only" placard was required on the 337.
Most of my customers made the jump from paper to an iPad, and have long since removed any GPSs
Yep, the drawings/blueprints in the Production certificate that state what is the standard. The P/C may be simply for a special nut FAA-PMAed after market, Prime example, the after market cylinders produced as STC or direct replacement.
Curious. If the drawings/blueprints/placards are listed in the PC, why are the specific requirements for these items listed in Part 23, 25, 27, and 29 for the issuance of a Type Certificate and not listed in part 21 Subpart G for the issuance of a Production Certificate? Also, if the PC is that important, how would someone produce a product under Part 21 Subpart F "Production Under a Type Certificate (without a PC)" if all the required information is in a Production Certificate that doesn't exist?

Read it again.
Production Certificate
A production certificate is an approval (document) to manufacture duplicate products under an FAA-approved type design (e.g., type certificate or supplemental type certificate). The holder of a production certificate may obtain an airworthiness certificate for aircraft produced under the production certificate without further showing. To obtain one, the production application and approval process must be followed.
Then answer.
Which came first? type design or Production certificate ?
And no you don't need a production certificate to build aircraft, many are built one off and certified on their own merits.
but they are not duplications. think about it. Waco
Ha. Type Design (i.e., Type Certificate). You can't even apply for a Production Certificate until you have an approved TC or STC. Take your pick: Order 8120.22A, Ch 3; AC 21-43; or, Form 8110.12.
Cessna used to sell copies of the certificates as a novelty years ago but haven't seen any in recent times. The documents are similar to a STC certificate and Operating Certificate.
Follow and read the links I've posted you figure it out.
Yeah. You've lived a sheltered life....
Has nothing to do with the certificate process. Entirely market driven. I can think of a dozen or so new aircraft models in the past 10 years. If you include LSAs double that number. But GA the market is flat. No one will pay $500K for a new model that does the same thing as a 30 year-old $80K aircraft. But new aircraft are certified every year.
Long story. But I'm feeling like a pencil whipped annual may be involved...
