Extra left legplate

Due to a momentary lapse of concentration, at the event I managed to buy two right-hand graves, I believe from Having A Larp. Somehow, I managed to fight the whole big battle without realising my mistake.

By the time I returned to the shop, their twins had both disappeared. I can only guess, therefore, that someone else is wandering around having just purchased two *left *greaves either shortly after or shortly before I did. I am looking, therefore, to reunite both sets with their long lost twins.

So, anyone with an extra left legplate looking to swap for a right?
