The Hungarian Factory was cominshioned to build 557Me 210's(C-1 and Ca-1) and 817 Me 410B-1's with 2/3rd's of all production aircraft going to the Luftwaffe.The 410's were howeaver never produced since most of the tools(jig's) were never sent to Hungery. Do to damage sustained in a USAF bombing atack only 270 210's were compleated and of those 110 were transfered to the luftwaffe, the factory was damaged to the extent that the production facility switched to just Me 109 production and then droped all firther Me 210 production. I beleave around 352 total Me 210's were produced so yes a fair precentage were from Hungery. While aprox. 1,121 Me 410's were built, by other Facilitys.
