As I posted in the original thread the following extract is from the Webley Spectre manual 'Do not apply lubrication to the air filler probe or the rifles air filler hole' also 'Use only mineral based oils such as Weboil(webleys oil) to lubricate the Spectre'.Now I use Abbey Gun & Rifle Oil.This is a light viscocity mineral oil with a powerful rust inhibitor additive(so it says on the can).I have been using this for a couple of years on a Cutlass for wiping the gun over & lightly oiling the cocking lever.Now should I bin it or keep on using it.Thanks,Steve
