As has been said,
If I "want" it, it is ok- I'll figure out what to call it later!
Shooter:
Generally Ed is close to what I'd say about a shooter.
Collectibles for me fall into two categories;
Representative: high % finish(could be period re-finished as may police lugers), matching(the mag is a +), no explanations required
Historic: variable finish, maybe re-finish, perhaps minor mis-match, but historic for some reason- scarcity, markings, etc.
Other:
Then there is the "zwitter" category, neither fish nor fowl; semi-collectible.
Could be a nice other wise collectible with a wart, like a bad finish spot, or a mis-matched major part. Or no finish, or pitted with cool markings, on and on. Could be called a historic shooter!
Others will develop their own system of justification and classification.
