Of course the way they framed the movie did not make this possible.

I thought Cap never had a vibranium sheild until he met Tony Stark? Nope

Again through retroactive continuity, it is established that the shield was presented to Rogers by President Franklin D. Roosevelt.[1] The shield is created by a fictional American metallurgist named Dr. Myron MacLain, who had been commissioned by the US government to create an indestructible armor material to aid the war effort. MacLain experiments with vibranium, an alien metal found only in Wakanda that has unique vibration absorption properties.

Rogers' indestructible shield was long referred to, even in continuity, as being composed of an adamantium steel-vibranium alloy. This contradicted earlier established continuity, as adamantium steel is only developed after Rogers is revived from suspended animation, during MacLain's later, unsuccessful experiments to try and duplicate the material of the shield. Adamantium steel makes its first appearance in Marvel Comics in Avengers Vol. 1 #66, July 1969.

The adamantium-vibranium error first appears in the Captain America entry in the Official Handbook of the Marvel Universe (the composition of the shield is accurately described in the adamantium entry as "vibranium-iron") and was propagated in several subsequent stories by writers using the Handbook as a reference. An attempt to correct this was made in Captain America #303–304 (March–April 1985), which establishes that the shield is made of vibranium and an experimental "steel alloy", but that did not prevent the repetition of the "adamantium-vibranium" description over the years.
