Candelabras - what are they made of please?

Hello,

I have recently purchased a pair of candelabras at a flea market in Paris.
They only seem to have one logo on the bottom - it is just an indication of the manufacturer, or is there a way to find out if it is metal or maybe silver-plated?

Please have a look at the photos:
