TR4/4A Ignition Switch for TR4A

[r66]

I purchased a replacement "NOS" ignition switch on e-bay for my TR4A. It turns out that it only has an "off-on-start" position instead of the "acc-off-on-start" position I believe TR4A's are supposed to have. I bought it to replace an obvious aftermarket switch I currently have. I plan to resell it on e-bay. Did TR3's have a 3 position switch? I am wondering if that is what I have.

TR3's had a 2 position switch (off and on) and a starter button.
According to my TR4A drivers handbook, they did have a 4 position switch. Vertical (12:00) is off, 1:00 is Ignition, 2:00 is start. Turning the switch counterclockwise from Off, to the 11:00 position is Auxiliary.
My recently sold TR4A just had a toggle switch and a starter button. /ubbthreads/images/graemlins/grin.gif

I suspect that this could be a TR4 or earlier Herald, etc., switch. Does it have screw terminals (early, usually no ACC position) or spade connector terminals? And what's the Lucas number on the switch?

The TR4 handbook shows a four position switch, same as the TR-4A.

Part number is not legible. Thanks for info, looks like I don't know what I got.
