Not quite all original, but close.  It appears the bumper area and front frame rail intersections have been modified.

UPDATE:  Still Available

(07/26/2011) This has a rear PTO and was a column shift before a conversion.

“Vintage 1946 Jeep CJ2A. One owner since about 1947. Regularly serviced. Garaged for all of its life and not used for the past 25 years. Engine has been started regularly. First civilian model after WWII. Had shifter on steering column, but has been converted to a floor shift. Original flat head engine has also been replaced with the overhead valve four cylinder ‘hurricane’ engine. Large rear mounted PTO winch. Otherwise, most everything else is stock. In great shape with a ‘Koenig’ steel top. VERY little rust, if any? Repainted, upholstered and gone over mechanically in about 1956. Seats can use new upholstery. Carburetor rebuilt in 2006. Doesn’t burn oil or leak. Tires are all pretty good. Rims have a chrome ring on the rim. Everything works good. Runs great. Great for original restoration or drive it as is. Serious parties please E-mail to discuss price.”

This appears in good shape.
