I'm not sure if this is the proper place for this, but I'm in need of a free to use photo of a 90mm Anti-Aircraft gun.
I'm currently working on a documentary about the Los Angeles Air Raid, which I've already got permission to show at the an event occurring this year, but I'm having a hard time finding any photos of this gun which is copyright free for me to use.
I'll be taking a trip down to a museum to take some photos of an old gun sitting outside, but I was hoping for a broader variety and am exploring all my options.
If anyone happens to have family photos of their grandparents using one during WWII or have access to one that they can take a picture of this would be greatly appreciated. Video of one in action that I can use would be especially awesome.
If not, I'm no worse off then when I started.
