I never really thought of myself as a collector, until yesterday when I decided to register all instruments I had lying around in my tiny home. I was a little bit shocked to discover I had 31 of them, more or less playable...
I put them in an app called "MyCollections" to keep track of them. It also gives the possibility to share your collection publicly. Here is mine:

(It only shows items with pictures, so my 2017 Wessex Festivo Euphonium is missing as I did not yet take a pic of it)
