Do you want to sale them?
depending on their condition the fact that they are belgium made puts your 16 ga in the years of 1960 to 1973
unless it is chambered for something other than 2 3/4" shells
then you wouild have different gun
Standard Grade Special Vent Rib 16 is worth in normal use field hunting condition unrestored at about $500
If your grade 1 is new in the box it might bring $900 on a real good day
If it is Marked on the Barrel Sweet-16 you can add $100 to the value
only the higher grade A-5s have a highvalue for an auto-loader

your 12ga is another animal
why do you beleive that is an early model? what size shells does it shoot?
If it is an early model you could expect about the same value as your 16
a later model after 1950 brings 25% less.
