HELP - Death Star Gun Turret / Turbolaser

Hey guys,
Lonepigeon and I are working on a big blueprint style poster project for DK and I'm looking for some Death Star Gun Turret Reference. for some detail drawings.

I've got the basic stuff but was wondering if anyone has recreated the nice detailed version of the turret and would be willing to shoot some reference photos for me. The MR Turret that came with the Y-Wing would possibly work as well but I can't find what I need anywhere online.

I'm hoping to get a nice series of straight-on shots of the top, front and side.

The big detailed one is/was on display in London and I've seen some nice 3/4 shots on Flikr but maybe someone has gotten some good shots that I haven't seen.

If you can help please let me know.

Thanks!

How about these:

Um... well I guess those will work.

Thanks! Looks like that was probably a fun day for you. Its an awesome place isn't it?
