Odd size Flare box/waterproof storage bottles
I'm after a pair of plastic storage bottles/flare containers for my A frame. I have a couple of S/s holders bolted on but they seem to be an odd size. The max width/dia. that would fit is about 180mm. Most of the containers I can find of a decent capacity are 240-270mm. There isn't much stowage space on the boat so they would be very useful. Any ideas where I can buy some?
