Hi Antipodal,
Thought I would chip in my opinion on why the ceramic. When I consider something like this I think "follow the money". Back in those days mica caps of that value were probably difficult to find and difficult to manufacture, pay big bucks to obtain. Another solution was to use the twisted pair wire but the drawback is not accurate enough. Ceramic was, and probably still is, the right solution, although temperature stability is an issue. But that can be accounted for. There's my theory. GL with the restoration.
