I found this type 1 SDR through the small ads. Sometimes I prefer to find lamps like this that have been well used with a bit of history. The tank has been crudely repaired with solder. It looks like the knob of the control cock was lost and something has been soldered on. The bolts holding the top reflector are missing and have been replaced by split pins. The edges of the top reflector look a bit rough like they were crudely cut but I think it is the original part. The base plate of the tank has a nice big dent in it. Must have been hit with some force to do that to it. When the seller told me he had a spare glass for it I thought I might end up with two original SDR globes but alas one is the non-standard 2081 glass that I will have to grind down. The other glass doesn't fit and I am not sure what it is for. The top cap is a piece of rust but I have a brass one around here somewhere. There is a chap in Korea selling orange caps who might be able to run me off a few black ones sometime.
