Its amazing what you find when your not looking, i searched for these for i dont know how long and always came up empty. I bought a few of these slider knobs years back and could not get any info on their source due to "NDA's". The other day i was looking for detonator knobs and this thing caught my eye. Now that i found it im sharing the find since im not under any agreements to keep it quiet. I think the lower single knob is also used on something but its not coming to mind.
