Hopefully you can read the embossing on these two well embossed J.H. WESTON // CIN. O single groove LRIs. Note the taper at the opening to the through hole. This is typical on the well embossed units. Notice too the typical color: aqua. Most often a rich blue aqua, but also common in a more plain aqua color. These are not rare LRIs, but old and have character.
