Question

i have seen on astromech.net, that on an original epsiode 4 picture, r2-d2 is standing with alex guiness in the desert. on this pic you can see, that the ankle details are way more flat, than they are on the club spec pictures and blueprints... what do you think?

here an ankle detail made to club spec:

and by the way; do you see the missing octagon port and the connectors in front of the battery box?
