Here are some pics of my IF542 which i finished earlier this year , in quite a bad state when i got it but nowhere near as bad as the FL-6 IF542 arrived today I'll finish the guard out of stainless wire soonish Stu
Have you got one to copy from? - they're not just a bigger version of the standard Tilley Guard. Similar, mainly, but with longer legs bent out to reach the edges of the larger reflector. And could you make a couple more while you're on...
