Is there a "flight manual" for a 46 BC12D? If so does it contain take-off and landing data over the proverbial 50' obstacle?
If not, where is that information found?

I have owned a BC12d since 1982 and in the late sixties, early seventies I owned a BL65 and I have never found any of the flight info.
One year I got an L2 manual thinking it might be similar data, not sure that was a good assumption.

Dave,
I know that for many older airplanes there are no "FAA approved" flight manuals not even a single paged one like my 48 Stinson. My L-2 has a military flight manual which I doubt is FAA approved. At least it has good information in it, including "how to bail-out". The reason I asked, is that a friend's girlfriend is getting ready to take her Private Pilot's checkride in her 46 BC12-D and the examiner wants her to figure out the take-off and landing distance over a 50' obstacle. He must be a young guy used to having that information contained in the flight manuals of more modern airplanes than the ones made in the forties.

There is a "Flight Manual" (as described by "NC36061") for a BC12D. It describes how to start, and how to stop the engine. That was all that was required "back then". It's one-half of an A4 or foolscap page.
As to the 50 foot obstacle, there was no requirement back then (in CAR days) for such a thing.
Or maybe the guy isn't young and uninformed. Maybe he wants to see how she answers the task. Just because the information is not published, doesn't mean it isn't important. Get with the instructor, do some short field work, and find out what she can do in that particular aircraft. In my book, that is more important data than anything published. If the guy isn't aware of the lack of published info on our grand old airplanes, he should be impressed when she says "This is what I have done in this aircraft and I will set my limits based on what I know I can do."
Edit: As I read this after posting it, I realize that it challenges myself to go fly and find out what I can do in my airplane after gaining a few years of experience.

Reason: Afterthought
In short, NO, placards only. The instructor just needs to be schooled a little on vintage airplanes. and the regs, then maybe he will not worry about the numbers so much. That is why my panel only has 5 gauges in it, makes a person look outside some instead of messin with radios and things....use a 150 book to do the calculations to demonstrate it and then fly the Tcraft with a smile!
If you're motivated, you can develop your own performance charts. I did this with my Tango and might consider doing it with my T-Craft. This is the book that I used...
The book gives you Excel formulas that you can use to create the spreadsheets that can be used to determine your performance. It also tells you how to get the data needed to create those spreadsheets.
The price has gone up to gouging levels since I bought it a bunch of years ago, but the Kindle version seems to be somewhat more reasonable.

Don't you hate it when you can't come up with something witty or profound for your signature??
For sure, I wasn't intending this for FAA use, just personal use. The process lets you find out just what you and your airplane can do.
If you have say 200-300 hours in the air , this airplane should be a cinch. It was an inexpensive trainer designed to teach the basic reudiments of flight. If you play around with it for say five hours , some at altitude, stalls , spins, etc, then do some landings and takeoffs , short field, soft field , etc. it's very easy to see how forgivable and docile it is. The fact that it has only a few basic instruments is due to its simplicity. Don't overthink it. Just have fun.
Google "Koch Chart" if you know s/l standard day you can then determine the change in performance based on temp and pressure altitude. A student with a Luscombe took the chart for his check ride. His perf. Calculations based on the chart were accepted.
