bullet: That is one of the reference images I posted at the start of this project. Check back on page 1. But yes that is the paint scheme I am planing on.

hammer: yes, I mentioned at the start that a tutorial for the arc gun exsisted some place, but I only saw a picture of the finished work (not as large as the one in the link you provided though).

This is my own version. I don't have the tutorial. You can see comparing the two mine is very different and significantly more accurate.

My model is based on the drawing (see starting ref images posted at the start) and has a number of differences from the one modeled in the tut.

Thanks for the references but I just want to be clear, I do not own nor have I ever seen that tutorial. This model is completely my own design using my own modeling methods, and is not associated with the version in that tutorial in anyway.
