Does anyone have a Dually headcollar/training aid to fit a 13.2hh pony? Red or possibly Green?

[Fifty Bales of Hay]

Does anyone have a dually headcollar/training aid to fit a 13.2hh pony, I think maybe a Red or possibly the Green (I've not measured) sitting around needing a new home please?

I am really interested in trying one, but didn't want to splash out on a brand new one if I can recycle one somebody has no use for anymore.

Thanks.
