So you've got the arrestor, the insulator mounts and the standoffs. What's the composition of the item far right? It looks like a vial of some sort. I've see tiny flasks like that, about four inches long that must have been used by ladies during prohibition times. My Grandmother had one, which I supposed was filled with moonshine. Might only hold two ounces but two ounces of moonshine in a small woman is plenty!
Nice finds and good luck MDJ!
