Pair TOWLE Sterling Silver Candlesticks Adjustable/transformable Candlesticks in the Style #735. 
RARE: Have not seen another pair like this elsewhere. 

Pattern #735

The tops are removable and they screw in to make them taller. They have been loosened from all the years, but is easily fixed by simply using a small strip of sarin wrap. 

Approximate Size:  
Diameter of bottom:  3.75" inches.
Diameter of height:    4.5" inches without the removable top.
Diameter of height:    9"  inches with the top on.
 
These pieces are weighted & reinforced.

Condition is good.  There are a few small "pings" but hard to see.
There are a few small "indentations" on the bottom of the base side.
Could use a more thorough silver cleaning.  
The actual white candles are not included.
