Just a quick post to say thanks very much to YHR, SNOWTANK and Swathdiver for your replies regarding my HL Pershing not firing at all, I know it was a couple of weeks ago now, but it took a while to get round to fixing it, and your info really helped (especially the scanned diagram!!) Tank is all better now and have added an extra piece of wire to reduce the tension on the ones that pulled out. Happy now!
