Antique Indo Persian Islamic Battle Armour (set of four pieces)helmet, shield, 2 battle hand weapons

I am really not an expert on these items....it is a shield (20 inches edge to edge), helmet (from pointed tip on top to helmet face edgeline (approx 10 inches)....battle ax (26 1/2" long  (blade 7 1/2 x 4 1/2").......and battle (devil head) club (26 1/2" end to end)....

This is a 4 piece set made of metal and looks very old

I don't really know what the name of these are and from what period....I would appreciate anyone's help on getting information of what they are  (description) and what they are approximately worth.

thank everyone very much
