Zimmerman "The Favorite" Vintage Autoharp, with accessories, travel case, key

Description

Zimmerman 2-3/4 "The Favorite" autoharp.  5 chord bars, 23 strings.  Quite dusty, until recently it had been stored in a storage unit in Los Angeles for probably decades; I found it among my stepmother's things when she passed away in 2017.
With tuning key, two picks, and a vintage storage pouch for them.
Original manual/songbook, with a few sample songs; there is some mold spotting on this.
Storage case may not be original to the instrument; it appears to be "folk art" style.
Shipped in a large box with lots of padding.  For reference, the case is ~21" long.
