Anyhow, someone let slip here recently that George Bennett has an example of the German variety of such cyclindrical slide rules. It is available For Sale, subject to offers of at least US$1,000. I've checked and can confirm this. He tells me it was useful once when surveying underground mines, as a relatively quick way of performing trig calculations there, in the days before small electronic calculators. Then again in Antarctica, for much the same reason. so its well travelled and has had some use, although presenting as in fine form - I've seen it.
Maybe someone could acquire it as a model for this hypothetical replica.

Always preferable to make Bygraves, if this is the only alternative. I hadn't realised that the carrying-out of these ignoble assaults was such a problem amongst us NavListers.
A wonderful idea. ...
It would be nice to do as a project simply for the sake of it. If nothing else it would give people something else to do other than going out mugging old ladies for their handbags.
