ID:	208008in the Zemplén mountains of NE Hungary where there purportedly crashed a Ju-52 in October of '44. I think that it's from the underside, because of the light-blue paint. This latest expedition was not our first to the site (Junkers repül).
Thanks to all in advance for any comments and advice!!!
