The top of the gauze filter has an outside diameter of an inch and eleven sixteenths, so it's a nice fit inside the metal cap that holds it down, which has an inside diameter of an inch and three quarters.

The cap dimensions, if you need to make one of those, are an O/D of 1 and 13/16", total height is 13/16" made up of a rim height of 1/2" and the pip height is another 5/16". The pip, that the spring turns and nips onto, has an O/D of 5/8" .

Ray, 
When you get chance to measure the oil filter cap can you give me the outer diameter of the gauze filter please?

I have at last found the C12 plates I knew I had somewhere! One hole (arrowed)has been welded probably due to wear. They are identical. I hope the photo helps, let me know if you want more details.

I never use the choke on any of my bikes, summer or winter. ........I tell a lie! My BSA/Indian special will not start without choke and you have to allow it to warm up as you ease the choke off......But that has a made up carb/manifold setup with a very long throat.  Ron

Same wheels as the 1940 C11, Ron, - WM1 - 20. They also had another tooth on the engine sprocket, to lift the gearing a bit more, a bigger bore exhaust and a two-plate clutch to handle all that extra power.

For some reason or other they were fitted with a choke on their larger carb but I've never needed it and neither did the road testers of the period.

One little flaw in my oil filters is the lip I left on the top.  Looking back at Rays filter it has no lip like the B20 filter on the top edge so will have to carefully machine that off.
I mistakenly thought the cap sat on the  top lip and now realise the cap sits over the top of the filter as Ray said in his last post.

I just compared a front plate off my basketcase C11 to my still assembled C12 project and the plates are identical. So not much point my sending a pattern. I just checked the parts list and both C11 and C12 list common number 29-4075

Technical Section / Re: C10 Regulator

You don't have to change any wiring when using a mechanical reg except changing over the battery connection.  However, when using a solid state regulator there are different makes with different ways of working. Some need the connections inside of the dynamo changed, other are a straight swop. Best to check with instructions.
Found instructions online  you were right the field wires do need to be swapped, hopefully it will still work, plenty of time to do it while all this is going on thanks
