If the gun had the "banjo" style fore arm release escutcheon; it was an ejector model. If there was a round dogs head bakelite insert in the forearm wood, it was an extractor model. Smith guns were not produced in 20-bore until 1907, so pre-1913 Grade 2/2-E 20-bore Smith guns were only in production for 5 years prior to the Grades change in 1913. I won't hazard a price, but if this 20-bore was manufactured on the old style Regular, or "R" frame, you could pick a value, as no "R" framed 20-bore has ever been discovered (and may not exist?). I can also tell you that 2E 20-bores are highly sought by Smith gun aficionados; generally hard to find, and generally fetch good prices.
