I know nothing about CPA quality, or the quality of work on this gun. What I do know is that a similar CPA, or original Stevens will run you much more than the $1,800 that this auction is at now.
The stock work may not be perfect, but it's much better than I can do. The engraving is not at par with some originals, or what guys like Ken can do, but again it's better than I can do.
Overall the gun has a nice look to it, and will certainly go a bit higher before the auction ends, IMHO.
And white line spacers are for new guns, not classic repros, or originals.
