What is This?

Does anyone know what type of eyepiece this is? It looks to be a fairly long focal length and a wider FOV than a plossl. There are no marking on it anywhere.

Thanks for any help you can give.

The shape, size and design of your eyepiece look very much like those of my 40 mm Celestron NexStar 1¼-inch plössl, but mine is clearly labeleled as such on the silver-colored band below the black rubber band in the middle. Also, I may be misled as to the dimensions of your eyepiece because it is too far from the camera and the measuring tape in your photo. Good luck in your detective work.
