The Ta 183 was designed by Multhopp not Tank. He and his right hand emigrated to GB after the war, not Argentine. Before he left Tanks team, everything that existed of the Ta 183 was tons of data and some models. Not even the final layout was fully agreed upon yet. No matter how much of a genius Tank was, he was at the time not nearly as firm in the field of high speed aircraft as the likes of Lippisch, Hornung or other people at Messerschmidt. As far as familiarity goes the Tunnan or MiG-15 can be considered just as much children of the Ta 183 as the Pulqui II: Not much besides the general layout and a probably varying amount of basic data was used.
