Identify a piece of armor plate from a Do 217 M

[BABIN]

Hello,

Could somebody identify a piece of armor plate from a Do 217 M with, on the front side, an inscription or part of an inscription, in big yellow letters (the word "nich" is visible), and on the back side a difficult to read "registration" : 37144C - dun.AU24 - 69

This piece of armor is not shown in its original shape: it was most likely cut off by its first owner.

Thank you in advance for any answer that could be brought to me
