Sylvania Lifeline 40w BLB tubes

These were from the massive haul from earlier on. I think they are NOS but they must have been sitting outside for a long time due to the corrosion on the ends. Only one of them actually worked however; one of the pins on the other just came clean off! I kept it in the hope of a repair one day. These are some of my favourite tubes from that haul, these old American blacklights are quite heavy.
