So this is a Chrome over Brass model???
The picture quality isn't the greatest... and I can't really see any brass peaking out from underneath the scratches in the chrome. Makes me wonder if it actually is a brass shell.
Also, to me, it looks like there is a bigger problem with the chroming based on all that stippling, it almost looks like Chromy (that's Woody Woodpecker's metallic cousin) was pecking away at a significant portion of the surface.
Are you looking at getting this from a retailer or private party? Just asking because if you can't get better pictures to assess the shell issues you may want some return protect.
