Hi, can someone please send me a photo of Ewarts petcocks as fitted to the 1969 commando S, cheers, David
 
Here's a pic of one I got with my Apr 69 S that I bought in Apr 72. I assume it's original, but I don't have them mounted as they leak and as I can tell there's no way to mount it so the lever is always to the outside. There's no room for even a thin nut to use for that.

I got some from clubman that look sort of original but shinier and they have rubber parts inside, but so far no problems.

I think the EW were mounted with fiber washers.
 
Yes, use new ones. You can use two reserve type taps. I have mounted a reserve tap on the left side and a normal tap with a piece of tube on the right side. I only open up the right tap when I ride. When I run out of fuel I open the left one. I noticed there is still much fuel in the right side of the tank which can't be drained because of that tube. So I guess I will remove it and get some extra miles. The fuel does not flow across the “ backbone“ of the tank.
