Stoppers for paddling pool appeal (Bradford on Avon BA15)

An appeal to anyone who may have broken a paddling pool this weekend! I have managed to accidentally recycle the two rubber bungs and twist caps from our inflatable paddling pool! The pool is a rectangular pool with two inflatable rectangular rings that form the sides - each with a small safety style inflation valve and a larger, round open inflation point with a rubber bung and flattish screw cap. If anybody has the bungs and or caps going spare, we would be incredibly grateful (and much cooler!). Thank you for looking
