I seem to remember a story to the effect that, some 40 years ago (a little before my time, certainly) my company's Sports & social club wanted to buy an upright piano (from club funds) and, we could get a good discount using the lab procurement system, however the rules would not allow the purchase of non-scientific equipment through the lab system.
The problem was solved when one of our acoustics bods wrote a purchase requisition for a "multi octave, mechanical digital tone generator" quoting the manufaturer's catalogue number, this was enough to get through the system.
I can't vouch for the truth of this story (as I say, it was before my time), but the S&S club does have a rather nice upright piano which had been doing sterling service since before I joined.>br>
