Insulated copper cylinder - 144 litre capacity

Purchased about 5/6 years ago but haven't lived in the house for last 4 years so it had hardly been used. Selling because we got a stainless steel cyclinder after moving back in. (42 x 18 G2) >> 42 inches in height, 18 inches in diameter. The "insulated" part means it has a layer of foam to reduce heat loss. The "G2" or "Grade 2" refers to the thickness of the copper used, indicating a standard residential cylinder.
