If you can find some roll-your-own with no printing on the paper it'll look original... :mrgreen:
I’m sure they have plenty of “roll your own” papers in Colorado, given that state’s GREEN laws. :lol:

We went to a Winter Solstice party with a "Cheap Date Night" theme so I drove the 1950 Pontiac, Ina wore 3/4 length pants with a fuzzy sweater and I dressed like James Dean with a pack of Camels rolled up in my T-shirt sleeve. I wanted to use Lucky Strikes but they are long gone, AND they did not have ANY unfiltered cigarettes. Big brother is watching out for you.

So, no authentic butts unless you roll your own.

I have no idea if the knob is the correct style or color. Does anyone know if this knob was rose or “coral” colored like the panel knobs on the ‘52 170B? It’s shown in Fig. 35-15 of the 170B IPC but the same p/n is in exploded view in the straight 170 IPC as shown below.

All of the trailing edges of the flight controls on my 48 are spot welded, no rivets (rudder, flaps, ailerons). Seems to be a somewhat "structural part". I have been thinking about the day I do a restoration and replace the skins, how to maintain the authentic spot welded look.

How many of you have spot welded trailing edges on your flight control surfaces -- ailerons, flaps, rudder, or elevators? I'm curious how late Cessna used spot welds rather than rivets on these trailing edges. I've heard Dillon Barron's '54 model had spot welded flight control trailing edges. My '52 has rivets on all trailing edges but it's also been through at least two wrecks so I have no idea if this was original.

I thought of this discussion which we had several years ago when I ran across this YouTube video. The tip on spot welding aluminum starts at 11:39.

Yeah, he really has some very practical/usable tips. Much of this is not the kind of stuff you learn in school; it's what you learn shadowing an old-timer around his shop.
