The sporran and plaid brooch may help others refine the choice.
I agree, Peter, the image is very dark and grainy. But having blown it up to the resolution limit of my screen, I can't see any trace of a red line - adjacent white grid squares look identical, so I'm inclined to think it's more likely to be Gordon or Lamont. That said, though, red often resolves to black in old monochrome film stock.

It does look to be a kilt pin, rather than a piece of bicycle.
