Genuine HECKEL key chain bassoon

Description

This is a genuine Heckel key chain that came from the factory in the 70s. I’ve had it in my possession all that time, but never actually used it for keys. It is stamped on the back Heckel.
I don’t see anything on it to suggest it is silver.  It’s in great condition as can be seen.
It could make a nice necklace piece or just left as a special keychain.
