Agree that your unfired BSS should bring additional $300 over the unfired Model 25-2.
I don't know about today's higher pricing, but I haven't changed my values on my guns simply because I think they'll come down a little when all the current "worries and troubles" slow down.
Another point currently would be you are going to pay a lot more for 45 acp ammo (and a BMT moon loader if you don't already have one) than your trading partner will have to pay for 12 ga shot shells.
My 25-2, 6-1/2", blue, patridge front sight Letters shipping Feb 14, 1972 and is a real sweet shooter. My gun (no case, no docs, no tools) is valued at $1,100 on my records and is at least a 95% gun....very tight lockup, throats are all decent without the oversize condition found in many others.
Good luck on the trade, post some pics of course if and when you get it. Who knows, maybe the 25-2 is one of the 1000 or so that were "mis-stamped" as Model of 1950, instead of Model of 1955...quite a bit scarcer I believe.
