Picked this one up back in July, out of Texas. Serial number is MO 3004-77S2522970. Appeared to be all original when I got it, changed tires to better and still correct examples. Front tire is Carlisle Super Ride 20 x 1.75" and rear is Carlisle Jet Flyte 20 x 2.125 grooved slick. Original tires were dated April 1977 so I am putting this bike at coming off the line in May 1977 based on other data I have collected on these bikes. The earliest 1977 Murray choppers came with the 3-slot fender, within a few months they revised the fenders to have 6 smaller slots (to be more durable I'm guessing). Enjoy.
