I re-categorized your question to Firearm from Optics.

From what I can locate on the internet, it is difficult to estimate the value. The serial number alone is not sufficient.

I believe Springfield was made by Savage/Stevens. If so, here is the date range:

iver johnson single barrel champion shotguns with a single letter suffix to the serial number were manufactured between 1920 and 1929. it seem that most of the 410 were used quite a bit and very few are in excellent condition. the original finish was an oil finished stock, browned barrel and case hardened frame.

CHAMPION MODEL 36--------------------------------1909-1922
Single barrel; rebounding center mounted hammer; top lever operated break open design; gauges: 12, 16, and 20; barrel length: 28, 30, and 32 inches (features barrel and lug forged in one piece) bored full chock only; American black Walnut but* stock and fore-end; automatic extractors; weight 6¾ pounds; overall length with 30 inch barrel 45 inches; case hardened receiver (nickel available as option), browned barrel; automatic ejectors extra cost option; .410 bore, 24 and 28 gauges offered in 1913; 24 gauge dropped 1928; all gauges except 12 dropped after 1941; name changed to Champion single Barrel in 1917.
CHAMPION SINGLE BARREL---------------------------1923-1978
This is the same gun as the earlier Model 36 champion except that the smaller gauges are now built on the same frame as the large gagues. See above picture for specifications. The exact year production stopped has not yet been determined. Some of these single barrel shotguns have been seen with Canadian marking, these were most likely shipped to Canada and then marked as there is no evidence that Iver Johnson's Arms & Cycle Works ever had a manufacturing factory in Canada

Would need more info these guns can range from $100 - $1000 some $5000 + depends on age, condition, model, etc... this is a good site to try and determine what you might have.... http://www.gunsinternational.com/Iver-Johnson-Shotguns.cfm?cat_id=632

According to this website (http://www.gundigest.com/gun-collecting-firearm-collecting/sqa-stevens-letter-prefix-serial-numbers) it sounds like it would be between 1913 and 1939.

It was built on the 1890 Hopkins and Allen patent and is very similar to several dozens of inexpensive single shot shotguns.

Some shotguns don't even have serial numbers, Make and model will tell more than a serial number unless it is a very rare piece. Is it an old Belgian Browning auto 5?? Something like that , you can tell.
