When we had the Bell target boom in the U.K in the early 1900’s what kind of short range indoor target shooting were the Germans doing with air rifles?

The beautiful hand made gallery guns became the Bugelspanner, which was still popular but that seems to have developed into a fairground gun.

As it was before WW1 I suppose there were no arms restrictions and a lot of Germans would have shot those lovely flobert Scheibenbusche target rifles instead of air rifles.

Any insight would be appreciated.

Cheers,
Matt
