This lamp is exactly like the Volcán 400 table lamp posted by Neil, but the brand is "El Sol de Noche". Volcán made the same lanterns and lamps using both brands and different model numbers, perhaps for regions where El Sol de Noche, a very old lantern brand, was more popular. Not easy to find with this brand. This lamp has no model nr.
I don't date them because I have no idea. Cuareta or volcán worked making lamps since the 20's until perhaps the early 80's and they didn't change their designs, just a few details like the enamelled ventilator, like Neil's lamp for sure were their last productions because the examples you find on the market are in very good condition. This is the only fact I know. Let's say from late 50's to late 70's, but it is just a guess.
