Working at a restaurant as the bartender - a profession which requires social diligence and flamboyancy - one tends to meet a lot of interesting folks.
So, while working under just those circumstances at a restaurant/cafe near to my home, I expected to maybe acquire some contacts for insulators through talking to people. I met up with a number of farmers, seniors, junk collectors, etc, all who frequented the place, and indicated they would be willing to part with some of their insulators. However, I didn't expect to befriend both the curator of a local museum, and a local historian through the job. The museum curator was nice enough to bring in a box of insulators he had sitting around which weren't being displayed, and pass them on to me as a tip for an evening of dining!
There were 4 insulators in the box - a Hemingray 40 in standard aqua, a Brookfield 152 with absolutely amazing amber swirls, but so full of cracks that light no longer passes through it, a Dominion -42 CD 154, and, surprisingly, this piece. My first thoughts were Hemingray blue or blue aqua, as I was looking at the  listing for H.G.Co. CD 162. However, it turns out I was short sighted at first, and had failed to notice the missing bar in the 'A' of 'MAY', making the piece the  listing! Coincidental that one of the few pieces in the box would actually be of interest from a collecting standpoint!
What's the strangest way you've acquired an insulators as of late. As a tip?
All the best!
