Any other source? That just says it was smaller, yes, by 1m. :p And also, that it had A-3's engine, seeing how A-3 was almost 7 meters long, I dont think the engine would fit to a ~1.5-2 meter long rocket.

Here's a quote from another site
http://www.zamandayolculuk.com/cetinbal/V2RROCKET.htm

By 1936 the team had moved on from the A2 and started work on both the A3 and A4. The later was a full sized design with a range of about 175 kilometers (109 miles), a top altitude of 80 kilometers (50 miles), and a payload of about a tonne. It was clear that Von Braun's designs were turning into real weapons, and Dornberger moved the team from Kummersdorf (near Berlin) to a small town, Peenemünde, on the island of Usedom on Germany's Baltic coast , in order to provide more room for testing and better secrecy.

The A3 proved to be problematic, and a redesign was started as the A5. This version was completely reliable, and by 1941 the team had fired about seventy A5 rockets. The first A4 flew in March 1942, flying about a mile and crashing into the water. The second launch made it to seven miles in altitude before exploding. But the third rocket launched on October 3, 1942 changed things, when the rocket followed its trajectory perfectly and landed 120 miles away, and became the first man-made object to enter space as well as the first man-made machine to exceed the speed of sound.

I'm starting to think that's somekind of dummy rocket for to entertain the brass. I've tried to dig any info about that for most of the day and it's like it never existed.

EDIT: Here's another pretty cool site about all of the versions of V2: http://www.astronautix.com/lvfam/v2.htm

EDIT2: And Hunter get's prize! *clap clap clap*

From the last link:

September 1939 - Peenemuende -. First A5 drop test. The model is dropped from a He-111 bomber from 7000 m. It breaks through the sound barrier at 1000 m altitude at a speed of 360 m/s. The stabilising fins keep the maximum oscillation of the model to within 5 degrees from vertical. The drogue ring parachute then deployed to decelerate the model to 100 m/s, followed by the main parachute which slows it to 5 m/s when it impacts in the ocean.
