Indicated Airspeeds...again

I thought it was about time to put the correctly marked ASI in my plane. It has had a Cessna indicator since I got it, and I want to have the correct color bands. I would appreciate if anyone has an originally marked air speed indicator in a Cruisair tell me how they are marked. From the manual, I would guess (?!!) that the red line(Vne) is 216 mph, the bottom of the yellow, (Vno) is 160 mph, and the top of the white (Vfe) is 85 mph. Are any original airspeed indicators marked different than this? What I don't know is where is the bottom of the white and the bottom of the green? THe book says that the minimum airspeed is 48 mph, but is that with or without flaps. I guess I could just go up and fly it and use my GPS and mutidirectional runs to figure this out, but would appreciate it if anyone has an originally marked ASI to let me know what it should be. Thanks! Larry
 
Larry,
Lots of the early airplanes had no color coding or limit lines on any instruments. I would bottom out the white and green arcs at 48 mph. This doesn't mean much as you can get any 14-13 and some 14-19 aircraft to fly at a bit less than 45mph, INDICATED. BTW, you can get the colored arcs from an instrument shop or ACS. Put them on the instrument face....not the glass.

I have flown my 14-13 at around 45 MPH indicated with and without flaps, and with and without power. I find unbelievable how docile and benign the stall is in this little rocket-ship. I could probably hold the joke full aft all the way to the ground and I would probably survive the crash.
With injuries of course...
What a REMARKABLE airplane!
And mine is flying again!
WOOHOO!!! :)
Who needs meth when you can fly a 14-13. It's twice the fun and just a little bit more expensive... ;-)
 
As a reminder...these are INDICATED airspeeds, subject to installation error.
45 IAS probably equals 55-60 CAS.

The stick ons from aircraft spruse are cheap and the way to go.

I have the colored speed ranges painted on the face of my air speed indicator.. works fine,
as long as you don't obscure any numerals.

Dan's way is the elegant way, but not a 10 minute way.

Dont forget to put a witness mark across the glass to the edge so you can tell if the glass moved.

most decent instrument shops will put the markings on for you at a reasonable cost..
