Why would they sell a gun brand new back in 1957 in a presentation case? I assume it sold to be used, not displayed.
Those cases are not very durable, I think they were pretty much for display and the initial shipping.
That satin lining is not very strong and repeated carrying or taking the gun in and out can tear it.
I don't have a pic of the inside of my 1956 case, but it looks the same. The box in the photo looks black to me, only the earliest ones were blue, however if that Model 29 was shipped in early 57 it is very possible they still had some blue boxes left to use. Also the sight adjustment tool can be either all black, like the one in he photo, or have an aluminum colored knurled handle.
Here is the way the first Goncalo Alves grips look.
I have a factory letter on mine and also sent Roy Jinks(the official S&W historian) a picture of the pistol case and tools. He assured me that they were all correct for my pistol which was shipped in July, 1956.
