Overall Condition: This shotgun retains about 93% of its metal finish. The barrels have strong finish with only light handling marks and some wear from the forend which is concealed when assembled. The balance is mostly in the receiver which has handling wear through the finish in the tangs, the trigger guard and on the controls. There is some other scattered light wear and some areas which have discolored. The screw heads range from sharp to lightly tool marked with strong slots. The markings are clear. Overall, this shotgun is in Very Good-plus condition.
Mechanics: The action functions correctly including ejectors. The lockup is tight. The safety does not return to Safe when the action is opened, but does function correctly when engaged manually. We have not fired this shotgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.
Box, Paperwork & Accessories: None
Our Assessment: Browning is not the only company to have found that Japan has some high quality firearms manufacturers. In the late ’60s and ’70s, Ithaca also contracted to have side-by-side and over-under shotguns made for them, choosing SKB rather than Miroku. The result is a fine-quality double gun with graceful lines, a nice balance and of course, strong mechanics. The Ithaca SKB model 680 is prized by hunters and sportsmen for its craftsmanship, durability, and has a straight grip, making it both less common and attractive to those who prefer an English stock. This one appears to have seen responsible use. In Very Good-plus condition it shows wear in the receiver’s silver finish and some in the stocks, but retains great bores and strong mechanics, indicating proper maintenance. It should prove to serve its new owner as well as it seems to have served its previous owners. Please see our photos and good luck!
