Zenit-E

The Zenit-E 35mm camera was made in the USSR. The Helios 44-2 lens indicates that it was probably made in 1971.
This camera is fully mechanical and fully manual, requiring no battery, including the lightmeter. I am sure it is still perfectly functional.

Can't seem to find much on the Bell & Howell Model 20 flash made in Japan, but it probably would still work too. It just needs 4 AA batteries.
