The first one is a brown ceramic and measures approx 4.5" x 1.5" x 2" high.

I can find no marks or damage to this piece. 

I believe that the second is a pewter boot that measures approx 2.75" x 1 1/8" x 2.25" high.

I can find no marks or damage to this piece.

I have not polished it.

The third is heavy. I believe it is brass. It features little mice on each side.

It measures approx 3" x 1.5" x 1.5" high.

This piece retains its original price sticker from Shannon Airport from when one of my family member's purchased it.

It also has marks on the underside. I believe Elpec Reg and a series of numbers. 

I have not polished this. It has a green patina on the underside from age.

Please do not hesitate to contact me for more photos or with questions.
