To get it roadworthy my plan is a lot like the one for my XS2 was. Take it down to the frame and then reassembly. Cleaning and repairing as needed. After the frame and suspension are done start on the motor. I know the top end needs gone through. It ran when I parked it. The middle cylinder would from time to time smoke like a mosquito fogger. Usually when there were a lot of people around. It was also the hardest starting bike I've ever owned. There's a trick to kicking the triples. It's a steel tank bonded to a fiberglass shell. When I got the bike the tank was full of rust. I remember using the ever popular Cream on it after cleaning the tank. I've been afraid to look inside it. I'll cross that bridge when I get to it. As far as how many made I'm not sure. I've read as low as 1171 and as many as 2300. According to my vin number it was built in December of 1972 as a 1973 model. Interesting note they were pushing to get as many built in December as they could. Any built after December 31 would have to meet different noise standards and have turn signals to be imported to the USA.
