IMO your rifle is the perfect candidate for a factory letter.
Fingers crossed,... the letter would confirm rifle grade, special, etc. and may even include plating.
Either way, the value of the rifle stays the same or doubles depending.
I also think a movie prop would be beat up. A prop wouldn't need a rifle like that. But, ya never know.
It's a special rifle probably owned by a movie star. The story got twisted somewheres.
