A specialty of my LRI collection. G.W. Otis Patented AUG, 26,1851 (the best in my opinion) Insulator for Lightning Rods No. 8,316. It's a historic day and I'm happy to post these in his honor.

These are most of the known point variations attached to Otises. Not shown are the Patent Model with serrations and a variation of the Double Wire style.

Enjoy whatever you collect...
