I think it was a childrens movie where these two kids (brothers?) were the heroes and the bad guy was like a victorian looking dude with sinister facial hair and maybe some kind of fancy hat, like a top hat, and a cane i think, all in black. I think maybe he could change his appearance, he was the devil or some kind of evil wizard. all i remember is the story / climax involved lighting hitting a lightning rod on the kids' house. thanks!
Personally I think it's a stupid idea. No one really needs a gun, I mean cmon what would you use it for?? Is there some one out to get you or something?? I guess it might come in handy when you're in trouble and need protection, but there's other things you can do besides owning a gun. Having a gun in the house is dangerous anyways even if you keep it somewhere really safe, sooner or later it's gonna cause issues.
Contact the manufacturer and ask them if there are repair parts available. Most manf. recommend replacing a helmet once a year. You can have it xrayed for cracks, rule of thumb is if you drop it on a hard surface, you should replace it,
There are tinny little filters/sensors to detect smoke. Just go and get new ones, after about 5 years they need replaced for you to be safe anyway.
