Optic light battery box 'fwq'
A very nice early to mid-war battery box as used with a variety of optical instruments, including the MG34/42 MGZ scopes, 10x80 Flakfernrohr and SF14 periscope etc.
Interestingly, this particular example has received a white camouflage finish over the top of the factory grey at some stage.
Internally, the field grey layer still remains visible throughout, as well as the 'fwq' maker code to denote manufacture by Saalfelder Apparatebau GmbH, Saalfeld.
All internal fittings and electrical connectors remain in excellent condition!
