These porcelain insulators were kindly sent to me by a website visitor around the time of the big "Q", and had lain forgotten in a smashed filing cabinet drawer until this evening. I accidentally "rediscovered" them while looking for some SMD LEDs (totally different website, folks). :)

The big one is marked "PP" on the nipple, and is 4.5" long. The other two are apparently unmarked, and are 3.5" long each.

Honestly, they look like crack pipes. Convincing the police they are really insulators instead of drug paraphernalia might take some doing. :-O
