My dad built one out of brass for one of our LGB moguls. I will be able to take pictures of it this weekend when I am home. There was also a company that made kits too but they are long gone. I will try to post the pics or if that doesn't work, I can email them to you
If you really want one (this is kind of extreme) go and purchase one of the LGB C&S Forneys or Moguls on ebay and remove the spark arrestor. Then, put the engine back on ebay and sell it! If you time it right you can get a decent price and may even sell it for nearly what you paid for it! (That's how I acquired mine!)
That is a great idea but a little to extrem for know but if I cant get one or make one that looks good that might be what I have to do.
I tried to call LGB and say that I had the Mogul and that it took a spill and the Bear trap broke they said they were out of them
Thanks for the idea
