Schmidt-Rubins are beautifully made Swiss instruments, just like their watches, and incredibly accurate. That being said, the action is, please forgive me, the ugliest classic factory action I've ever seen. It looks like a cross between a veterinary instrument and a plumbing tool. Definitely designed solely for function, not looks.
The thing that always nags at my mind about them: Given the experience of rifles like the Ross, I can't help but wonder how they would have fared in the mud of Flanders. The examples we see today have never been to war. They've been meticulously maintained by highly-trained and dedicated servicemen. I can't help but wonder how long they would have functioned in the hands of hastily-trained conscripts under arduous and filthy conditions. Luckily for them and us, we never had to find out.
