Yeah the 25 is a nice light and NOS makes it that much better. I never saw this on ebay. Do you have a link to the auction? I've always wanted a model 13. I like the medium fixtures but i've always prefered the small sized lights for some reason plus they're easier to store so i can have more of them!
Oh nice. I found a listing for a nice NOS Hubbell RMA too here. I like those lights but i don't have the cash or room right now. I have a light on the way right now.
Hinge assembly was changed over in 1985 starting with the Model 113. The 13 was discontinued around that time. The only light that has the original hinge (with the wire restraint) is the 327.
I like medium fixtures the best, but they are harder to store. Most of my collection is in a storage facility now.
