Hi!
Nifty Z50
I purchased it second hand in 06/01/1971 so therefore it is not a 71 or 72 model.
The badge is the same as your, oval with "Monkey" on it.

The frame numbers is 278306 or 218306. I cannot read the 7 properly. I've tried with a magnifying glass. I cannot tell if it is figure 1 or 7.
No clutch lever, it's automatic.
Have alook at the photo.
ALSO please note that turning idicators are not it. Took them off for safe keeping.
Bike a little bit dirty, sits in shed, covered up.
