Hey mate,
I'm fairly certain I have the opposite problem. As I recall, I have a folded link jubilee bracelet in my spares that has been extended with a section of oval links (3 or 4 oval links from memory). I remember being disappointed when the bracelet came in, the repair hadn't been declared by the seller and wasn't obvious in the pics .
I'm back home tomorrow, will check and talk to you then. Might be an option for swapsies
