HIC 10

Found at Castlecary and kindly donated by John Crozier.

This is a 6 chambered ensemble and I think it may be for service cables such as BT rather than sewer or water but I am not sure.

It measures 32″ long, 18 1/2  x 13 1/2 inches at widest points ( across the broken lip).

Each large channel is  4 1/4″ in diameter and the small openings are  1 1/4″ in diameter.

It is marked HIC 10 which I believe was once the trademark of Hepworth Iron Company.

I am uncertain if this was manufactured in Scotland or elsewhere. Hepworths swallowed up a good number of Scottish Companies. – GR – Stein among others was a member of the Hepworth Ceramics Group.
