Went to BOC this afternoon as one of my cylinders toppled on the garage the other week whilst moving stuff about (yes, I know I'm a tit and it should have been secured!) and this did for one of the gauges on the reg. BOC it seems, can't sell me a gauge on its own as this makes them and me a 'manufacturer and then we'd be liable if anything went wrong'? I was too tired to ask what he meant and really couldn't be arsed anyway so came away. I've found several on eBay but remember seeing something on here about eBay regulators being iffy so wanted to check if this went for gauges as well?
