I've seen and sold one or two but that's all: we made a point of gradually getting in one of everything as well as lots of the mainstream stuff. From memory it looked exactly like the 300 but had a very slight recoil. More or less in the same way that (say) the Walther LG 55's and the HW 55's recoiled meaning nothing you'd notice.
Looking at the little instruction manual that came with the 200 and 300, the makers don't seem to distinguish between them. Just a rifle that could be either is shown in the booklet. And the "Company News" announcing the 300 doesn't mention the 200.
Sorry I can't help more than that. What's really annoying is that we found the old sales register in November last year and realised that we ought to be thinking (again) about clearing the loft. Now we've started, and are working through about two dozen boxes of papers etc, I've lost the sales register. If I had it in my grubby hands I could tell you how many we sold and who to...
