Great old right angle finder with many touches Unitron used that makes me think it was made by them. 30mm coated objective with a nice blue tinge, deep recessed objective, removeable 0.965 machined diagonal--even the edges are machine beveled, removeable 6 power eyepiece with the cross hairs in the eyepiece.
