POTUS knows where and when the missiles were bought. All manufacturers of them have "End of Use" documentation. Each part on the missiles have lot and part numbers silk screened or etched into them that identify where and when that part was made and who it shipped to. That part number can be tracked all the way to it's End Use. Unless these were stolen missiles , the seller and date sold is immediately available.

The speed at which POTUS came out and said they were purchased with BHO 150 bil money means that at minimum, a part used to make the missile was manufactured in the USA. Iran DID NOT build those missiles, they bought them. The parts to build these missiles are extremely HIGHLY regulated and would not be easily allowed out of the Country. It is highly UNLIKELY that SOME USA manufactured parts were mixed into a Russian missile and work. Therefore, if POTUS is telling the truth, and these missiles were bought at or around the time Iran received the 150 bil, they were USA made.

POTUS could not get date manufacturing/sale to determine a Russian made missile this fast IF EVER. He could however, spend about 10 seconds searching the data base of the DOD for part numbers to get any and all info he needed to make the claim.
