Here's another one I found in my archives. This is from one of the replicas that was made along the way - MR perhaps - I can't remember. It's significantly different than the other one but supposedly accurate to something.
Still looking back on all RPF etc posts , found this tested video which shows replica being created which looks like the source of these 2 shots, interesting for me, maybe old news http://youtu.be/JQwLcOJBNL0
screen grab I took from it shows the v12 and this variant
