Here's my lightning arrestor display, all but the glass one were found on railroads. My most recent addition is the largest one on the far left. It was on a downed pole up on a hill/cliff with some fuse cut-outs, 3 M-2210's (none of which i could get) and of all things a transformer that had been smashed open when the pole collapsed. The arrestor is a GE.

The Large brown one to the right of it was found on a nearby railroad with 4 (damaged) others. The hardware for the glass one was obtained by smashing one of the damaged ones to pieces for the hardware.

The glass one was given to me at the springfield show last year, i think. Now i just need the larger size glass one.

And on the very far right, the white ceramic one. This is a MacGrawl-Edison, or somthing like that. Found on an abandoned Indiana railroad.
