I've seen this question asked a lot but with no clear answer. The only reason I bring this up as a new topic is because at the time I purchased mine (April 2016), there apparently was a transition period where Photonis was being bought out. At the moment I ordered the PVS-14, the website still listed it as a Photonis tube and that it also came with a spec sheet. After placing the order, I found out it would not come with a spec sheet,l. I asked if they could possibly tell me what model tube the Photonis I have was. They informed me that couldn't guarantee that I got a tube that has Photonis markings. At that point I wondered if I bought the PLUS model and paid for a Photonis tube, but may not have received a Photonis tube. I'm not making acusations, just maybe hoping for some clarification.
