Shocking Question

[ArtS]

I want to throw out a blasphemous question for general information.

Has anyone ever seen a Parker 10 gauge bored out to 8 gauge? I have seen people that have taken modern Matador II , I believe, doubles and done this.
The thing that piqued my interest was that I won an auction several months back for an average looking late lifter that was advertised as a 12 gauge that turned out to be the heaviest 10 gauge I have ever seen. It has untouched Damascus barrels, the gun is in really nice condition and the barrels are literally like sewer pipes in thickness. After boring and rechambering, it would have walls everywhere in a normal 8 gauge range. I already have 2 8 gauges, a Scott and a Webley, in a high grade and in excellent shooting condition. Problem is both are so old ( both 1871-1872) that neither were built with choked bores. I know the argument about degradeing a Parker, but 10 grade lifters are not a rare commodity. I have 6 right now. With the costs of a functional 8 gauge, the economics would likely lay in the direction of a conversion if I decide that I want an 8 gauge with more long range performance. With what I payed for the 10 gauge and the boring/chambering costs I would have around $1700 in a gun that could only be determined to be modified by checking the serialization book. There is no way any solid useable 8 gauge could be touched on the market for that.
