Liberty Cycles Cyclone muscle bike Serial ID help needed

[ChiknCoop]

So yeah, I wasn't going to buy anything until I finished the Dragster but umm, I ended up with an original Liberty Cycles out of Chicago Girls Cyclone muscle bike. I'm trying to figure out what year it was made. Also can anyone tell me if these frames were made by Chicago Schwinn or Murray? I've read both, so I don't know. I've attached a pic of the serial numbers on the dropout.

oh and that first letter is a M

Murray built, not sure on year.

Thanks, that was a huge help, I was able to find out that it's from 1966.

"In 65 they were changing there serial number style and by then they were on the left rear dropout. Some 65 bikes had an MO5 which stood for Murray Ohio 1965. After these 3 digits was a 2 or 3 digit model number followed by an X and a 1 or 2 digit number"
"MO5 = 65
MO6 = 66
MO7 = 67
MO8 = 68"

Schwinn did have a Schwinn-Liberty head badge, but I believe that it was many years before the space bikes of the late 1950’s to late 1960’s or so. Axle washers!
