Probe Droid arm positions?

Got the Sideshow probe droid and trying to match up screen shots and tour shots of the model with arm locations and getting
a bit confused. I don't really trust their instructions on accuracy of position for some of them.

Were the full size and model identical?
did they move arms later by the time the model went on tour?

Anyways, is there something definitive that is clear?

How do you like it? I was thinking about picking this one up.
Any pictures to help explain your concerns?

I like it greatly, some have complained it is too light. It is more a model kit styrene or PVC construction and not a heavy resin statue. But I'm totally good with that.
The bottom could have used a little more detail, it's just ok.

The two main large arms I'm pretty confident where they belong in relation to the outer hull, but the other smaller arms are where I see conflicts.
One arm is keyed with a smaller diameter then the others, so it only goes one place, but when I look at screen shots or the model it seems it belongs somewhere else.
And the smaller arms are a little more confusing to tell them apart. Everything is numbered but I think the instructions do not quite jive with the numbers on the parts.

Maybe someone can tell if this looks correct?.....

it's based on the 1:1, not the model.

Here's crops from some ILM negatives:

Thanks.
I think I am gonig to spend some time drawing things out to get it straight in my head and see if it maps properly onto the sideshow droid.

This might be of some help - since there is a tutorial in assembling plus an instructions sheet from SSC: http://www.therpf.com/showthread.php?t=190579&page=2&p=3412334&viewfull=1#post3412334
