What are your opinions on this 1950s 283

I don't see any holes where the missing index was, and to my knowledge they aren't typically glued. You usually see numerals (ex 12, 3, 6, 9) and markers combined while this one has just the 12, which kind of looks in disproportion with the rest. Also the Swiss Made text looks too small and not enough of a curve, at least from what I can tell from the photos.

I'd vote for a redial. Not a bad redial though if you can ignore the small issues. However that missing index is gonna be hard to replace, redial or not.
