Don't know the cfm rating, but that's just a common two barrel found on late 70s Ford/Mercury 302 engines. Probably in the 350cfm range, similar to the "universal" Holley 350cfm two barrel still available from Holley.
I've found a R-9111, and R-9112, but not a 9117. Those (9112-9111) were the 4360 series, 450-465 cfm econo carb #'s. This # is from off of the choke air horn?
Researched deeper...FatHack is correct, 9117 - 2300 series, Mid 70's Ford passenger, Truck, some AMC's and Mercs. Hygrade Kit # 1210
