On your Savage/Stevens Model 59, the Standard Catalog of Firearms says:
Exc. - $125
V.G. - $100
Good - $75
Don't be discouraged by the low $$$ value of this gun. It was an inexpensive utility-grade shotgun, and really isn't a "collector" gun. However, I've found that are certain guns in my collection that just "fit good", like an old pair of sneakers, and it has nothing to do with the dollar value.....they're "just right", and a pleasure to shoot. Keep it, shoot it, and enjoy it!
On your FIE CBC .22 Auto.....FIE was an importer (Firearms Import & Export), not a manufacturer. What I think
you may have is what they marketed as the "GR-8 Black Beauty"
. It was a 14 shot, tube fed, semi-auto with a black nylon stock, patterned after the Remington Nylon 66. It was made by CBC in Brasil. Does that sound about right?
If so, the Blue Book values it at:
98% - $75
95% - $70
90% - $65
80% - $60
