I posted a thread on this item recently, but it quickly degenerated after the photos I provided led to a quick and piercing interpretation of the glass. This time I have provided a good selection of high-quality photographs of the object, which will hopefully lead to a more intricate discussion on the piece. It has now been determined that the glass is highly likely to be Czech Bohemia crystal. It has also been determined that the swastika has been engraved via the copper wheel method, which completely rules out unskilled sand-blasting or easy etching. I myself do not that this glass came from a concentration camp, but I do believe that it is a period piece with a period Third Reich swastika. I have been searching for glass experts all over the internet, but most of them seem to offer valuations only. If anybody on this forum knows of an expert or source that would be able to help me uncover the truth behind this item please let me know. I will greatly appreciate any help or guidance on this piece. Thank you.

All the best,

Duncan.
