A 1930's era J.W. Fecker target telescope with 10 power. The overall length is 23" with a 3/4" tube and 1-3/8" objective bell. The protective aluminum end caps are fitted. The optics are clear with a standard cross hair. The blue has some small marks in it from use and handling. The Unertl style mounts are marked with the J.W. Fecker name. We have only this one used example. It does not have the period wood storage box.
