The Colt SxS's are fine guns. A price of $2.5k of a Grade 2 does seem too high unless it was in very high condition. For any collector gun in high condition the advice and guidance of experts is advisable.
I collect Parkers and LC Smiths and very often seek the advice of more knowledgable collectors of each. The Parker Gun Collectors Assocition at ParkerGun.org is where the Parker guys live. The LC Smith Collectors Association at LCSmith.org is the place for Smith knowledge. The Colt association is at
www.ColtCollectors.com Unfortunately, there is not much information there on the fine Colt shotguns. Try the Parker or Smith sites and somethere will probably also be a Colt shotgun collector.
Once again, $2500 may be too high for a Grade 2. I missed one last year for $1000. Now that was a great deal!!!
