😀 😀 😀 Re the above.. Here’s an interesting bit of gen.. I was talking to an SOC/VMCC member from Ulster today ref this problem and he casually mentioned that the gauze’s act like the ones on the old type Davy miners lamps.. IE not letting the flames through (therefore igniting the incoming charge) Now I find this intriguing as in an earlier life I worked the miners lamp room at Ollerton Colliery. We live and Learn….!! 😀 😀 😀 Ted
