Another Metal Detector Find

Here is a very interesting item I dug up with my metal detector many years ago in Corpus Christi, Texas, at a downtown building project. As you can tell, it has been in the ground for many years. These are probably the two valves of the top of an old match case. There was a bottom portion that slid into this portion. This could have possibly also been a business card case. As you can tell, this is made of brass.
I cleaned this with a process called electrolysis, here is more info on that, for those who are interested:

Here is what I find intriguing about this little item. One side is engraved with the famous Anheuser-Busch “A”, St Louis logo. The other side has an engraving of a Pullman Palace Car, see the name on the car? This is a very intricate engraving, somebody did a great job.
Here is more info on them:

Below the Palace Car is the name Adolphus Busch, which I am sure you all recognize. Here is some background on him.

I have not found another one this personalized yet. Could this have belonged to him personally? Why have your name engraved on this to give to someone else? Was this a gift to him from another person, possibly somebody at Pullman?
Questions, enjoy
