Picked up this anniversary clock a couple months ago. Measure 15" tall. Obviously missing the dome and the dohicky thingy that holds the pendulum. Pendulum was wrapped in a local newspaper page from 1956 when I got it. Face says Germany as does the back but no make. Also has the number 51149 on the back. Any idea where to get a replacement part and if it is worth fixing? Also age and make? Thanks.
