this is the design they had all the way back to WW II and carried it through at least the 60's if not another 20 years past that. B&L out of Rochester, N.Y.
It has both METAL lense caps, focuses smooooooth, 27X straight eyepiece, 60mm obj, paint is well, prolly 50 yrs old and used.....but I don't see any dings and the lenses are nice, focuses as it should. I used one similar in my BE days in my 5 gun Pachmayr box. I don't think you can duplicate the optics for this price, $190 + however you want it shipped/insured.
May trade for another 46M or 10m ssp rifle. Also H&N Finale .177 pellets..........$$ going in logical direction - of course.
