Kienzle Luftwaffe clock in Wooden Prop section

I have been checking what machines used the Kienzle Fi. 23886 clock and the list includes He72, Gliders, Fi 156, He111 and other aircraft where a navigator needed a clock.

So is this clock mounted in a wooden prop section a post war construct or are they both from a Luftwaffe wooden prop aircraft ?

Unfortunately it is glued in so I cannot access the data plate on the rear.
