Would like a Tele Vue 55mm plossl,please contact if you would like to sel or trade for a es 11mm 82 degree with box.caps etc in excellent condition the only thing with it is the barrel says nitrogen purged and the green button says argon,contacted the company about this and was advised that optically there is no difference but the nitrogen would take 70 to 80 yrs to leak out of the ep and the argon would take 80 to 90 yrs
