Old Opera glass

Old item while Taisho period(1920) comes out from my junk box, probably this was used by a noble woman to watch some theatrical and opera in ancient time before the world wars. The assembly structure by a specific craftmanship with manual one by one assembly does not permit disassembling so easily as in the mass-production goods seen here and there. The failure is the rusty screws set in the center of focusing mechanism, once loosened it would be possible to clear all of the optical lenses in side. Though chemical lubricating material has been applied there, heating method would be done if black enamel paint might be peeled. Anyway, this cute Opera glasses would be repaired and maintained into like new soon.
