Not sure why it matters or if it matters regarding the sale price, but it is a Lew Horton special order. A total of 250 were manufactured with 2.5 inch barrels for Lew Horton in 1984 under product code 104212.
After posting the above I went away for awhile and thought about this auction. IF an early 2.5 inch 686, pre lock with combats, matching box, papers and tools in new or LNIB condition is on your grail list, then you better go for it. This gun is 30 years old and only 250 were made. How many more opportunities will you have to get this gun in this condition? If you are a collector and this is what you want, then this one is certainly one to go for! If you are not a collector then it's too high as you can get comparable shooters in this configuaration for much less. I think b****f knew what he was doing.
