Job lot of offcuts of what was mains water pipe but useful for eg in a ditch to allow water to run through under a path. 

Not sure how many bits there are (as difficult to get to at back of shed and don't want to get it all out till we know if anyone wants it) but the bit in the photo is about 7 inch wide (inner diameter 6") and 67 inches long.  There is at least one bit that iis 11 inches wide (inner diameter 8 3/4").  Around 10 bits at least.

To be collected from Dunmow, Essex.
