Wondering what it's worth. This is a Star FM .22lr in excellent condition with the box and magazine.

A few years ago,5+, the last time I checked, they were bringing good money. Very well made. 350-500
Check Gunbroker, completed auctions best bet today.

Not many on the market and somewhat collectible given condition and having the box…very well made ..I’m thinking $350-$400

In my considerable experience of Stars, the short barrel is very uncommon.

www.gunboards.com has a site for Spanish pistol collectors and enthusiasts. I suggest your ask your questions there (you have to go WAY down their list of sites!). NICE little Star!
