Go to Browning's web sight. They have a page that will tell you how to read their serial numbers. I just found out that two of my brownings were made in 1981 and other neat fqs!
Only the "light" Twenty" had a gold trigger. My 1964 Belgium Browning Light Twenty has a gold trigger.
A good shotgun.

you will have to call Browning. Sn does not follow normal convention.
The standard mod 70 had a Winchester bead front sight on a ramp base with a sight cover. The standard rear sight was a Winchester 22G open sight. The rifles chambered for .375 H&H Mag had the Lyman 6W folding rear sight. Model 70 National Match (chambered for .30-06 only) had a Lyman No. 77 front sight on a forged ramp sight base and a Lyman No. 48WH rear sight. All receivers were tapped and drilled for popular scope and iron sights. The Model 70 Super Grade had a Redfield full gold bead front sight on a ramp with sight cover and a Winchester 22G open rear sight. (with acknowledgement to The Gun Digest, seventh edition, 1953)
