Attic Find

[bwood63]

While cleaning out mom's attic I came across an old airline travel bag. inside I found 2 cameras and a couple of lenses. A mini tripod and a GE exposure meter.
The first camera is a Dacora matic 4D.
The second camera is an Exakta VX IIA. It has a Carl Zeiss Tessar 1:3.5 f=5cm.
There is an Olympus Zuiko C. 1:3.5 f=4cm. No.62004
The last lens is a Soligor Elitar 135mm f:2.8 Telephoto. with covers and original box.
The Meter is a GE Type PR-1.

I am relatively new to photography and have only really used digital.
Any info would be appreciated
