Thanks for the detailed post. After owning an early 50 for some time, I felt that the low power to gun size ratio was unreasonable (8fpe) and eventually parted company. I thought a to1 would be an improvement and have sought one regularly, but I don't think it's the gun for me. I still think the best Diana/rws gun of its time was the 45, hunted with mine for 20 years, all thanks to john darlings review in SAR
