We have a very cool older trumpet with great patina. I’ve used this for display in my business for a while but want to see if someone else appreciates it?? It is marked Grand Rapids Michigan near the opening but can’t see another name , so guessing that is the name and production location? It’s silver, grey, and some coppery brass coming out on some areas of rubbing - the cool parts are the silver plated mouthpiece and the mother of pearl finger buttons ( there are 3 larger circles and 3 smaller circles). All buttons appear to work normally and sounds ok (not a player). Trumpet is about 21” long, about 5 3/4” at its tallest, 3” wide and 4” opening of the horn - it weights 37.50 ounces. I can see 2 small dings in the metal - see photos.   Serial number on #2 -- 89186 --- with the help of a kind ebayer,  it is estimated to be from 1927 --- not bad for 99years old???
