One Extremely rare bulk fill Co2 Armigas model 61 (SG) 8mm cal Smooth bore.
These are VERY hard to find I have only ever had one other.
This one is in very good condition.
I have made one brass shell case to fit or to be used as a pattern for others.
Some very minor damage to the end cap cover knurling and the locking stock screw has sustained some minor damage.
Try and find another one!
