Herschede 8day model Plymouth grandfather clock

I have a Herschede 8day model plymouth grandfather clock.
It appears to work, but is missing the pendulum. It has 2 stamps on the back, 400 and 488. The clock inside says that it is made in Germany.

I would like to know anything I can find out about this clock, including when it was made, how much it is worth, and if there is a pendulum that can be found.
