Franchi Spa 15
Supposedly between 100 & 150 full size, 22 1/2" barrels with fixed butt stocks and 50 compact size, 18 1/2" barrels & side folding stocks. Of the 50 compacts, reportedly 39 went to the US Gov. with 1 kept as a sales sample and the remaining 10 were sold to collectors.
Here is 1 of the 10 Franchi Spa 15 compact, new / unfired in the original box. I was fortunate to have fired some of the other guns and kept mine new in the box.
