Autoknips IV and V?

[JPD]

What's the difference between the Autoknips IV and V selftimers? Does the plunger in the "IV" slowly press the shutter trigger, similar to the "I" and the "V" immediately after the time has elapsed, like the "II"?

Sheesh, I guess I'll have to buy both and find out myself. :rolleyes:

I could use this thing myself. Are they still being made by someone?
