Dear collectors all over the world, At this moment there are some discussions about date codes stamped or scratched on lamps. To get a good overview what is correct or not I want to ask everybody to take some time and write here the numbers found on their lamp including a photograph of the item. To make it a little better to handle I would suggest we start with lamps made by Hipolito S.A.R.L. Portugal. At this moment restricted to the brands: Hipolito, Geniol and Camel. No discussions about the codes, I think we should first collect the information and then see if we can crack the code. @Reinhard already made a good start but we need more codes to validate and check. Off coarse other brands will follow so you all may already check those too. ps Also lamps with no code are important.
