Antique brass whale oil lamp

A month ago our laptop PC wrake down while I was posting this lamp. We bought it 45 days ago to Pablo Gigena in about 50 U$. You can find similar ones at the web http://www.ebay.com/itm/Antique-Brass-Whale-Oil-Lamp-/321220863102?pt=Antiques_Decorative_Arts&hash=item4aca41647e
or https://www.etsy.com/es/listing/170535054/antique-solid-brass-4-burner-lucerne?ref=market. For us it is very expensive, but it is very dificult to see one. Several years ago I got the opportunity to buy one at around the same price but I did not. This time we bought it. My grandmother had one but much smaller of two burners. This one has three burners, the top with a hand and is in very good condition. It has a pair of scissors call despabiladoras in Spanish, a pair of tongs and a hard piece of wire. There are no marks. About 1850, because later whale oil was replaced because of it cost. It is high 46 cm. If there is some expert that knows more about it is invite to tell us.
