Italian Cap Gun

so i have this very old cap gun (maybe even primers) that is itailian made. it cycles the feeding strip and the pin works so i have no doubt it would fire. any of you guys have any info on this thing?

here is a pic of it, mines in a little better shape but exactly the same. ony stampings on it are GT on the grips and "Gun Italy" on the "slide".
