Rising (Ex)Aspirations6 May 2008
A few years ago, I got it into my head to collect working Mannheim slide-rule tie-clips. I believe that, as of to-day, I have secured at least one complete exemplar of every variety of such that was made for resale.Yester-day, the clip whose acquisition I was celebrating arrived. It is of a somewhat different variety than any of my previous acquisitions, which is in-and-of-itself a good thing. But I had used the word
completeadvisedly. I have a slide-rule tie-clip that is missing the indicator (the clear, sliding thing used to check just how the graduated pieces line-up) with which it was originally sold. I was expecting a complete exemplar of the same variety. Instead, I have one that is altogether new to my collection.
So there is at least one sort of which I continue to lack a satisfactory example.
