Thanks very much for producing a truly excellent video which is also very informative which I think would be of interest to even a non-enthusiast due to your lucid narration.
I have a Diana Modell 6 and a FWB 65 and they are great examples of superb engineering and ingenuity.
I feel this has prompted me to use them more often.

Much appreciated and I hope you continue to produce more videos of this nature featuring other significant Airguns as you certainly have a talent for presenting this type of thing.

Cheers,
Graeme
