[concours] Badge Bar for XK 150

Good Afternoon:

My 1958 XK 150S OTS LHD, S830975DN, is nearing completion.

Is a badge bar an allowable accessory, i.e. no deductions?
If yes, is there a required type/or method of mounting
which is required?

Finally, if allowable, is there any rule re: the badges
themselves for concours. I have a VSCCA badge which I
would like to display.

Thanks,
Jim

P.S. I posted this question on the XK forum, as well–
