I may have struck paydirt! There's a surplus warehouse in Syracuse that may have the glassware I am looking for. When I spoke to the guy, he told me he'll sell them to me for up to $20 a pop. Oh, and I won't be having them shipped, If this turns out good, I am going to schedule a vacation day next Friday and drive up to Syracuse to pick them up myself.
Nice that you can get the refractor for less than you originally thought! Also, I think it's safe to say this arm passes the weight test. How heavy is this light? Also, nice collection of photocells!
I'll be making the drive to Syracuse, New York to pick up two M-1000 refractors from National Grid in Liverpool.
