I had one of the early 34s with an early TO trigger, may have been a TO1 trigger (or not), 1991 year of manufacture, in a Model 45 stock and was called the Model 45/34, in .177. It was a pretty accurate, powerful with a beautiful build and finish. It was one of the early 1,000 fps .177 caliber break barrel air rifles and is more powerful than my Original Model 45.
I think the German air guns, i.e. Diana and Weirauch are among the best mass produced air guns available. They will retain a good portion of their value, if you buy a good "used" example. I traded my 45/34 for an almost-new Savage MKIIG in .22LR last summer. Sometimes I wish I hadn't. You can buy a Savage anytime, but they don't make the 45/34 anymore.
