I just bought a pair of guns, including an Ithica/SKB 200E 20-ga. Special Skeet with very nice engraving and a 12-ga. marked New SKB Gun Co. Model 400, side-plated boxlock with choke tubes. Both are like new with the original boxes and the price was too good to pass even though I have no real need for them. I have a couple other regular 200E's but this one is much nicer so I'll probably use it for my occasional round of skeet.

My question is on the Model 400. I cannot seem to find any information on this gun in my internet searches. I find some Model 400's that are true boxlocks but noe with the side-plates and choke tubes. Anyone know anything about these? Maybe approximate dates of manufacture, some guess as to value, etc?
