A wood extension with grain and figure that doesn't match or a conspicuous line between the extension and the original stock may be a "wart on the gun", high quality extensions can look extremely good. John Foster in the UK did some beautiful ones. Pete Kogut in New Hampshire did a couple of fine ones for me, but I do not know if he still does extensions. Currently, Mark Larson in Tacoma Washington does the finest work of this kind. The joint between the extension and the stock is seamless and, with his skills as an artist, Mark perfectly matches the grain and figure. On work he has done for me, it takes a lot of study to see that there is an extension, rather than a 14 7/8" original stock. Beauty is in the eye of the beholder and people may have different preferences, but you can see Mark's work by Googling Mark Larson Gun Art.
