1862 model Oil Lamp Complete!

Lamp is in perfect condtion with no kinks, dings, dents, chips or any defects! T is patina and soot residue on the brass parts but that is it. The top open and closes with the clasp and hinge in perfect working order. The tough part is I can not find any makers marks on any piece, so suggestions are welcome! I will also send you detailed photos on request if t is something particular you want to look at. On the wick adjusting knob it is embossed OCT.14.1862.. on the inside of the face and PAT.JULY 21.63. DEC.10.67.. on the outer face and both are very clear and legible. Measures 5 1/2 tall and 4 3/8 diameter at the base. *****I will be listing many items clearing out my house and barn after years of collecting. I will combine shipping. I accept PayPal, money orders or checks but nothing ships until a check clears. I live in SE Wisconsin so if you live in the area and want to pick up your item you are welcome to do that to save on shipping. Buyer pays actual shipping from 53040 and I will mail worldwide. I will consider parcel post or book rate for some items, just ask! I want to keep this cheap and easy for both of us :) I guarantee every item as described and will answer questions or email additional pics on request, but please don't wait until the last day :)
