While a nice plate, it's definitely not a Bf110 main ID plate. The stkz/code on the display frame's tag, and on the Bf110 in the photo, is M8+ZE. A number of such framed souvenir pieces were made, showing different photos of this airplane as found in Russia in the 1990s, and including various plates perportedly from the wreck. The W.Nr. of this particular Bf110 was 4502. Can't say for sure if the photo-framed plates were in fact from M8+ZE/4502, but it's possible. Plates with different W.Nr. on a single airplane is the norm. Typically, the W.Nr. are for individual parts, not the plane's main number, thus all different. Alternatively, such part plates did sometimes list the plane's main number, and parts from different planes were known to be intermixed during maintenance, repair, and model upgrade, etc., possibly bringing plates with different main numbers onto the same airplane. There was speculation that 4502, an E-model, or parts thereof, may have evolved from an earlier 110 C-model with a different W.Nr.
