classic quality too!
The 6x42 designation and the type of reticle shown in your pics indicate a Deer Stalking scope (made in the Czech Republic BTW).
Meopta are one of the very best European scope makers and always have been however, I know of few models that are entirely suitable for air rifle use - generally they would have a minimum focus stated as @50 yard
Your example looks like an 'Artemis' Meopta, if that helps.
