I would guess at 7 speed, but the way to find out for sure is to screw off the cover on the RH lever and count the number of notches on the index ring inside.
Can't tell for sure from the angles in the pictures, but these look like the first version before they increased the diameter of the cable pull on the RH lever to accommodate 8 speed shifting.
Spacing on 7 and 8 freewheels/cassettes was the same; I am currently using 8 speed levers with a Regina America 7 speed freewheel on one of my bikes.
