Solid brass .45 Colt dummy

I have had this .45 Colt dummy in my collection for several years. It is turned from a solid piece of brass; the ‘bullet’ is painted silver. The case is a tad short, but otherwise the dimensions are right. Other than the ‘primer’ not being quite centered, it is quite well made. Can anyone tell me if this a toy, a movie prop, or possibly the product of someone with too much idle time and access to a lathe and a supply of brass stock.
