'Non-Period' is NOT an 'anachronism' or 'goof'
Okay, IMDB, time to just stop the gun freaks (and other history fanatics) from designating out of period weapons and other items as "Goofs" in a work of fiction.
Guess what dudes, first of all, these are productions of entertainment, not records of history, or even documentaries. Most productions are NOT EVER going to be able to obtain perfect examples of all physical items for a story set in the past - it's simply impossible.
So just stop pointing them out as goofs, in this case "close" IS good enough.
If you want to note that items in the production are not perfectly authentic, then simply do so in the message board or review portions of each production's pages.
IMDB, it's really stupid to call these authenticity issues, "goofs".
Second of all, "anacronisms" are NOT items which are LITERALLY in the wrong time period (which of course is currently physically impossible other than in the movies!), they are items which SEEM out of place in their current context, like a superhero driving a Model T rather than a supercar of some kind, or a computer programmer character using a typewriter and an optical scanner to enter code, rather than a computer keyboard. An anacronism has to be visually or otherwise obvious, not just a fact of history that seems out of place.
Yes kids, words have proper meanings and functions when you use them correctly!
