Oil drum 210 litre (or similiar) (Presteigne LD8)

I am building a Japanese garden. An oil drum with the bottom cut out, primed with galvanised paint painted with bitumen and lined with geotext will prevent the spread of bamboo for 25-30 years. Short of using reinforced concrete, this is as good as one is going to get. Given I am 64...


Anyway, I am looking for about
o 10 × 45 L
o 3 × 90 L
o 3 × 210 L
 So even if you only have one or two, I would like them.
