LOT Pile of Asst Various Vintage TRUMPET Brass Parts Mouthpiece Slide Valves 30s

Description

A pile of assorted brass and other wind instrument parts. Most of these are from old trumpets or maybe valve trombones, including a set of valves and buttons and numerous slide bits. I acquired them in a box of 1920s/30s drum accessories and they are likely from that era as well.
There are also a number of woodwind parts and lyre sheet music clips, and a few modern accessories like slide oil and a reed.
I know very little about any of this and there are no visible brand markings on any of it.
Price is for everything shown. For sale as a lot only, sold as is.
