I tried to keep an inventory list of about 20-30 spare freewheels but it kept getting out of date when I would buy a new one or give one to my son. Most of my good parts are on good bikes. Any parts not on bikes are spares, kept in a few boxes. My general policy is to not collect or hoard. Keeping and updating inventory lists is too much like the job I retired from.
BTW, I really got a kick out of reading the other posts in this thread.
