This is not a working shell. It’s inert and hollow as seen in the picture. I repeat, INSANE ITEM! This lamp was made from a spent WWI era shell. I’m told it was used both in the WWI field and later as a US mining lamp. This is our favorite lamp from the estate. We are NOT old lamp or mining equipment collectors or experts. These items are listed as seen, with large views of all angles, right, left, back, front, top and bottom. Only the parts seen on the items are included. We do not have extra parts and we do not know if there are any missing parts or if the seen parts function, are the correct parts or if they are broken. If you are unsure of an item, it’s condition or value, please consult an expert. For 99.9% of items, we don’t. Thank you and good luck!
