I've never seen any official geometry , except that I own a copy of something called :

'77 Super-Lite Bicycle Specification Book
Schwinn Super Lite Bicycles

It's 8 1/2 inches by 11 inches , color , semi-glossy , with fairly stiff covers . If you include the front and back covers , there are 12 pages .
Models covered :
P13-9 Professional Road Racing Paramount P14-0 Professional Track Paramount P15-9 15-Speed Mens' Deluxe Touring Paramount P65-9 15-Speed Ladies' Deluxe Touring Paramount P10-9 Mens' 10-Speed Deluxe Tourer Paramount P60-9 Ladies' 10-Speed Deluxe Tourer Paramount T29-9 15-Speed Deluxe Tandem Paramount [ "men's - mixte" ] T32-9 15-Speed Deluxe Tandem Paramount [ "double men's" ]
Volare [ Reynolds 531, Shimano Dura-Ace, built overseas ] Super Le Tour 12.2 [ "Schwinn Approved" overseas ] Superior [ chromium molybdenum, hand fillet-brazed in Chicago U.S.A, 28 & 1/2 pounds ] Le Tour II [ built overseas ] Traveler [ "Schwinn Approved" basically a "Continental" with a lugged frame made in Asia , in my opinion this bicycle did not belong with this group ]
On the inside back cover , are frame dimensions for the 1977 Schwinn Paramounts ( none of the others , just Paramounts ) .
Listed are the ; seat tube length , top tube length , wheelbase , two frame angles , bottom bracket drop , and fork rake , for the three groups of single bikes . The P13 is all by itself . The Touring models are all grouped together . The Track is all by itself .
I won't try to type out everything .
I don't have a scanner .
These measurements should be all be exactly the same for all years from 1972 , through 1979 . Wish I knew about 1971 .
Schwinn consistently called the seat tube the "seat mast" . Schwinn referred to bottom bracket drop as "hanger drop" .
Every 1977 Paramount had parallel 73 degree frame angles , except the Track Paramount . It had parallel 74 degree frame angles .
Every 1977 Paramount had 3 inches of "hanger drop" except the Track Paramount . It had 2 and 1/2 inches of "hanger drop" .
All 1977 P13 Paramounts had 1 and 3/4 inches of fork rake . The 1977 P13 :
seat tube - 23 inches top tube - 22 3/16 inches wheelbase - 39 15/16 inches
seat tube - 24 inches top tube - 23 inches wheelbase - 40 3/4 inches
seat tube - 25 inches top tube - 23 1/2 inches wheelbase - 41 1/4 inches
All 1977 Touring Paramounts had 2 inches of fork rake . The 1977 Touring Paramounts :
seat tube - 23 inches top tube - 22 3/16 inches wheelbase - 40 9/16 inches
seat tube - 24 inches top tube - 23 inches wheelbase - 41 3/8 inches
seat tube - 25 inches top tube - 23 1/2 inches wheelbase - 41 3/4 inches
HEY! CHAINSTAYS!
Looks like the difference in the chain stays , between the P13 & the Touring , is 3/8 inch , for frames sizes 23-inch and 24-inch , and 1/4 inch , for frame size 25-inch .
Looks like I got it right with my little tape measure !
