I checked mine and it does have the Star of David stamps as shown in the above pics...never noticed the marks before!
Mine came with a no-name rubber wrap-around grip (with finger grooves). My number starts around the 5xxxxx range. Put a solid (2 piece) guide rod in it right away (back then) and allen-head screws in the grips. Otherwise, its all factory. The factory magazine is black with a metal/flat bumper like most 1911 magazines. Its been a solid shooter for several hundred rounds and don't ever recall any malfunctions with it. With its age I've started to think it may need new springs, but haven't researched which spring(s) to get for it :(. I also dry-ran a few of my newer magazines through it recently and some magazines would not feed properly (10 rd McCormick? can't recall) but my other 1911s had no issues with any of my magazines, using the same method. I know the real test would involve sending rounds down range and letting the slide do its thing, but with its age, I am thinking it needs springs anyway. It wound up set aside as a project while a new 191, not necessarily better, took its place (a scandium bobtail).
The factory uber-small plastic box has a Star of David on it and also has Model 5000 on the box. Paid just less than $400 back in the day. Also, I always liked to think I could see machining marks on the levers and slide (you?).
