Vintage 1973 Fisher Price Activity Center Busy Box 134

Description

I have cleaned and detailed the entire toy with wipies and swabs, with the exception of the inside of the acrylic windows.  I removed the screws on the back side of the toy, and it looked like prying the front and back apart to clean the windows would damage the toy.  The mirror has a few tiny spots of corrosion and rust.  The bell also has a few tiny spots, and one larger spot as shown in photo.  (I have never seen a copy of this toy without some oxidation and rust on the mirror and bell.)The lithos all show a little wear, and the litho on the spiral spinner is bubbled.  Everything works perfectly.
The soft plastic air button on the left side is not dented-in like most are.
The silver paint on the logo and around the outside edge is worn off.
The clamp that screws into the back to hold the toy to the crib slats is present, and there are no straps or ties.  There are slots or holes in each corner, and one could easily thread zip ties through the slots to attach the toy to the crib.  The plastic has many typical scuffs and scratches, and the back side has some discoloration.  While I do not know the forty-five year history of this item, it has no trace of smoke odor and I believe that it came from a non-smoking home.
Please ask any questions before buying.
