This thread is a godsend! I just bought this kit at a yard sale for $10.00 (yes; ten dollars!). You are being very clear about the kit's shortcomings, and I appreciate it very much! You are doing an outstanding job!
This is how I plan having little windows in false gun-ports with no guns. I plan same construction to all stern ocre color windows as well. Each window is individually made and inserted into the opening with some back supports to hold window from falling inside.
By the way Mamoli instructs installing a gun there where I installed a small window now. It is an office space there and no gun would fit inside. On current actual Victory there are windows there with no guns.
