SS Y-Wing front cannon size

[Redfinger]

I am working on a SS y-wing. I would like to use brass tubing for the front cannons. I count 6 or 7 different sizes. Does anyone know what the sizes are?

I have searched most of the y-wing threads, and have not been able to find the size, lots of good images though.

Happy Pre-Thanksgiving! Front fuselage is done! Panel details, torpedo shroud, and front cannons built and ready for final glue-up. Temporary assembly pics too. Once I get greeblies on the nacelles, the pipe bending completes major construction. I can see the light at the end of this tunnel...
