Yes, the eBay listing is ok.
Sometimes it is not easy to be sure about a very early Perthshire Paperweights item, but in general the cane setting looks to be more "compacted", or "tightly set". When the canes are in a more open setting, it usually suggests an early to mid (or even later) Strathearn, or a Vasart Ltd item. As for Ysart Brothers (first period Vasart) weights, they have a "look and feel" of their own which is hard to explain in text.
Of course, all the answers (or not!) are given in my web articles directly available through my "web icon" on the left
