Although you have,nt shown us a great deal of the binos,they are indeed German 6x30s, the condition on any Binos from WW2 is all important, these appear to have been through the mill a bit. Optics play a big part in value, you could have a pristine exterior but foggy optics so you need to assess the condition of the lenses , As they stand I would say an estimate of £45-50,,,, with very clear lenses perhaps £60-70
