This listing is for a Velox Glass Photo contraption.. I do not know a lot about the item other than it has been in the family for years. It would be used to produce photos onto glass as a negative. I have included what is a broken glass image that I assume has been produced using this machine. I have taken a number of images so that you can determine the condition and anything that may be missing, note I have put the item together as pictured also. Comes with original instructions and from that I believe this is dated towards the early 1900’s however please do your own research on this. Thank you for looking and I’m happy to tray and answer any questions
