I can just about recall Dartronic Ltd. They made test equipment in general. Here is an ad. for their 'scope model 381: it dates from about 1961.
I've sent this in mainly because of its construction: I've never come across a 'scope that uses the method illustrated. I can see that it makes for a compact construction, but I have a few doubts about the mechanical rigidity and ease of maintenance, though, despite the claim in the advert.
