I am a wierd sort I guess, but I love 101s. I shoot em, sell em, and every chance I get to pick one up affordably, I buy em ...The blue book doesn't do right by the 101(but geography does come into play here a wee bit). Fact is that the older (JAPANESE) 101s are very collectable in their own right, and they appreciate faster than anything else I know of bar none. I joke that they are the only merchandise I know of that makes me money whether I sell them or not, because they make money just layng on thr shelf appreciating... I collect them for this reason. I have Field grades(which is what you have) , Pigeons, Diamonds, Grand European(501s),
Trap Combos, Skeet Combos, Light Magnums, Light weight Pigeons, etc etc etc
If you go to some places in the USA some guns cost less there than thery might cost here and vice versa, hence the geography I spoke of. For instance, I know a fellow who buys as many Winchester lever action rifles as he can every time he goes to Oregon and Washington and brings them home to Va. for a quick $100-$200 profit on the average model '94 in 30-30Win. cal. He swears by this and I believe him, as I have seen a few of these little idiosyncracies mself. That said, the blue book can't keep up with appreciation of collectables fairly OR the geographic oddities.
Your gun looks to be in fairly good shape. If it is a Mod/Full choke it is worth about $1000 in Virginia (retail price* + or - a wee bit). It is probably worth considerably less in the midwest so I hear. 101s did not start screw in chokes until the late 70s or early 80s, so yours did not have them , and it has been my experience that in MOST cases, it is difficult to put screw ins into them, as the bbl walls are not thick enough to allow it safely. But I would not believe the thing about subtracting 60% without screw in chokes at all-- unless its on a late model 101; ergo a Belgian 101(which really is not a 101 at all)*--even the blue book gets room for errorsThe gun may be worth a tad more if it is in skeet chokes or trap chokes. But condition is everything in all of them; and yours looks pretty good, not much wear in the blue. I hope you love it as much as I love my 101s. Hell, I even gave my wife a 3 bbl Pigeon Grade skeet set for a wedding present.... And they say I'm not a romantic type...
* .(The Belgian 101s are like trying to make a 57 Chevy today---ya just can't do it!...That is my opinion--and ya know what they say about opinions---like a _ _ holes--everyones got one and most of em stink!)
