Why not size it with he turret to see if its a match? You can put em next to each other to see if the scale is correct? Could save a lot of time, be interesting to see if its close?
What about the m41 walker bulldog? For the scout droid....looks like they cut part of it off!!
Haha I was thinking the same thing. I just can't place which pen.Wild guess on the long thruster things with ribs - screams marker lid to me..
