Deep pot or metal bucket (Dinnington, S25)

I'm looking for an old metal bucket or jam pot or any deep pot.

This is for cloth dyeing so it doesn't matter much of the state as long as it can hold hot water and be put on a stove, it's all good.

Ideally 40cm/16inch deep. Diameter isn't much a problem.

Can collect evenings and weekends

Thanks.
