As part of a large consignment of telescope gear that was recently donated to EAS, there was a very small set of eyepieces--most of them less-usual types. Among them were a (suspected) Paul Rini 15mm, a 30mm 80-degree AFOV eyepiece that looks suspiciously like an old University Optics eyepiece, and the following Edmund 32mm Erfle. 

 

I'm curious about this one; it's got an unpainted barrel that has been pretty tarnished, and the only one I've seen (online) that was similar had a black barrel. Is this one of the military Erfles?  Does anyone have any idea of its vintage and/or value?  Although the barrel is nicked and tarnished, the glass looks pretty darn good given that it was stored in an attic uncovered for quite some time.

It’s not a military erfle (I had a couple long ago) - it’s simply an early Edmund one. Looks like the lenses are uncoated, and as it’s nothing special optically nor collectible, it’s value is purely sentimental.

Put it in a scope and enjoy the view.

Good to know. I didn't expect it to be worth much, but after a daytime test in a (similarly-donated) 12" Lightbridge, it seems to be a pretty fine eyepiece.

I think the zip code keeps it from being very old.

Pretty neat ocular regardless of its value.
