New Ride AMF Roadmaster ID and information needed.

[Shogun]

I have a new ride for the wife and need some information if possible. The best that I can tell is that is is a early 70's AMF Roadmaster, SN: T4788(1or7)6, it has Roadmaster on the chain guard and what is left of some print on the down tube. It has Ukari 27x1 1/4 W/O wheels and a Shimano 3sc with a coaster brake rear hub. I'm trying to figure out the year and the model of Roadmaster, and possibly what the writing on the downtube said, and also the place of manufacture.

Boy does that look like the Wards Hawthorne frame I fixed up over nine years ago, removed the Shimano 333 internal rear wheel and put a single speed coaster wheel on it. Nine years later it came back to me and will go to my niece.
