Besides the instruments and their accesoires I have a number of models, pictures, coins and stamps in my collection depicting the 'real' instruments. I do not count replica's in this category as a replica is a recreation of a real instrument. The models are usually scaled down to give an impression of the real, full size, instrument.
These are scaled down versions of 'real' instruments. They are used to demonstrate the instrument or used as decoration.
Toy instruments are modeled after the real instrument but are meant to be played with.
Some stamps and coins depict instruments. In a few cases the coins are not real but are geocaching coins.
Jewelry adorned with instruments.
Images of instruments on photographs or on objects.
