I have an 18k gold watch (Festina) that was bought in the 1970's from Spain that could no longer be repaired. What is a good ball park figure at the current rates this week?

2 old table lamps.  both glass bodies, one with 2 brass cherubs

A mint piece of "Sweet Adeline" sheet music signed by Harry Armstrong along with note to Frank von Eif saying "with kindest wishes from the composer Harry Armstrong N.Y. City, Aug. 4th 1943.  It also has the musical notation of treble clef with notes and sweet ad-el-ine under it

Small sized Perfume Bottle, from Paris. Comes in case. Never been opened but perfum has evoprated. From my research it could be as old as 1900's?

Electric -Corded boat clock. Over 50 years old I believe.  Lights up with on/off switch

Purchased this plaque from a seller when I worked at an antique store in the late 80's.  He had four of them (different scenes) but I only bought one and the other three sold in the store. It was not framed to begin with.  

The plaque is approx 12" wide by 24 high.

It appears to have been poured/hammered metal but I really have no idea.

I was told (take with a grain of salt) that is was originally part of a series of panels that came from a theater organ in St Louis.  Internet searches on the old theater organs has not yielded anything definitive.

When removed from the frame, the metal is fairly thin (1/16" inch) and pliable.

I have never polished or used any kind of cleaner on this.

Would be interested to know what it actually is (if anyone knows) and an approx value of the piece.
