discontinued by the manufacturer?
go figger......woulda thunk that 3 would have satisfied the entire world's demand for these....
Here's a warped thought:
we design, build and use what are referred to as pipeline pigs. 2 stories are used to explain why they are called pigs, and like so many, neither is verifyable and both have elements of truth as well as incredulity.
1) when a certain type of pig is in a pipeline, they squeak ("squeal") as they rub along the inside. Like a bare butt on a steel slide......
2) pipelines are inspected by measuring the inside dimensions, looking for dents (among many other things) that can lead to corrosion, cracks and other nasty things. The term "Pipeline Inspection Gage" was shortened to PIG.
Things of a pig motif are quite popular as office knicknaks in the industry. Having been in this industry a relatively short time, I'm not there yet.....
However, I am known a bit around work as the train photographer....so this might be an appropriate kickoff for my own PIG collection......
lord help me.....
