I believe that you are asking where the main airframe identification plate (typenschild) was located on a Ju 52. Start with the exterior of the forward fuselage on the left side. The plate was riveted to the flat skin forming the lower half of the fuselage side, aft of the nose curvature and below the cockpit canopy and adjacent corrugated skin. This relatively large plate measured ~ 4-in. long by 1.5-in. high. An examination of period pictures will often reveal it. A detached example (Werk-Nr. 6935) is pictured here.
